Raspberry Pi boards have revolutionized the electronics hobby world with their simple credit card-sized DIY computer kits. Today, almost anyone with a basic electronics assembly and coding knowledge could set up a Raspberry Pi system of their own.

In order to create a small computer of your own, all you need to have is a raspberry pi board, a display unit and a keyboard (optional). If you are able to find the perfect touch screen, you can create a great DIY computer of your own.

Today, we are going to list down all of the best Raspberry Pi compatible LCD screens available online. These screens are ranked and rated based on the following factors.

Rule of thumb, larger the better. The best of the LCD screens for a Raspberry Pi we got here have a 1080P high resolution and is a full touch screen. There are higher variants available as well but we believe that this is a standard benchmark.

The next important thing that you need to look for in a screen is its compatibility with the various systems that you may be using it other than the Raspberry Pi.

First on our list is an LCD touch screen straight from the official house of Raspberry Pi. It is a 7 inches large touch display that is specifically created for the Raspberry Pi board.

Though compatible with all the existing Raspberry Pi models, the hole line up for installation is good enough only for Raspberry A+, Raspberry B+, Raspberry Pi2

Yet another Kuman 7 inches HD Display Screen, this one is quite different from the previous Kuman display screen. That difference is not just in the screen resolution but in a wide range of other things as well.

Next on our list is 1 large 10.1 inches LED Display. The Elecrow HDMI supported LED display monitor supports all the old and new Raspberry Pi models like the Pi 4, 3, 2, and B, B+ models as well.

Apart from Raspberry Pi models, it is also compatible with PS3, PS4, WiiU and XBOX360 and can also be used for video, for car headrest and as a small display for medical equipment too

In this entry, SunFounder comes with a 10.1 inches large HDMI supported IPS LCD display monitor. It has a high resolution of 1280 X 800 pixels and also comes with a camera holder stand.

Next on our list is another SunFounder Raspberry Pi Compatible screen. This one is a simple 7 inches large LCD Display screen with built-in speakers too.

Next product on our list is from a brand called ELECROW. Their LCD screen comes with 5-inches size display and high-resolution picture. It is a resistive touchscreen monitor and comes with a touch pen for easy use.

This LCD touch screen is from SunFounder which has similar dimensions and aesthetical aspect as the previous 10.1 inches Screen by SunFounder and are essentially the same. This is just an older model of the same product.

The last but not least product from our list is a 7-inch LDC touch screen for Raspberry Pi. It supports mini PC like Raspberry 1B+ / 2B / 3B / 3A+/ 3B+/ 4B.

But it’s up to you to take the correct decisions as per your requirement. To make it happen, you must acquire some knowledge in technology stuff which becomes very easy for you to pick the right one.

Given below are some of the factors that most of the people ask for while purchasing the Raspberry Pi display kits. Get to know about them in detail to make a good choice.

The very first one in the buying guide list is the Price. The price of the displays tends to be more expensive because it comes with the number of features like resolution, size and many more.

So when you make a purchase, check whether the device is within your budget or not. If it so, then you can happily add the item to cart and wish for it.

But the problem arises when you are unable to afford the money or willing to use the item to fulfill your basic needs. For them, we provided the raspberry pi display kits that come with amazing features at very low prices. Read the product information to know which product best suits your requirements.

Brightness refers to the quality or state of reflecting a light. In other words, brightness can be expressed as the perception elicited by laminating a visual target. It can also be expressed by considering power over a specific area on the monitor. Most of the displays have 200cd/sq.m which is sufficient for a normal usage.

Contrast Ratiodefines the ratio of luminance of the brightest to the darkest color. Generally, the displays are capable of producing high contrast ratio as per the desired. You should also know that there are no specific standards to measure the contrast ratio.

Display resolution or the modes is the number of distinct pixels in each dimension that can be displayed. It is controlled by many of the factors like CRT, flat-panel displays, and LCDs. If the resolution you opt is not compatible then the monitors will stretch and shrink to fit in the specified. It turns result in a great loss of the signal and quality.

Like regular displays, the raspberry pi displays make effective communication between the peripheral devices. For this, it makes use of the connectors. The most common connectors are HDMI, VGA & AV-input. Each of them is illustrated below.

A VGA is a 3-row connector that is provided on many of the display devices like computers, TVs, laptops, and projectors. It is a good quality cable that supports the signal within the bandwidth range of (2-MHz-500MHz).

In this section, we are going to show you exactly how you can connect your Raspberry Pi to an external display screen. First, let us look at how to connect it using an HDMI port

Using the HDMI port to connect a Raspberry Pi to the LCD screen is one of the simplest and easiest ways to go. Here, all you need to do is to take an HDMI cable and plug it on both sides of the devices. One end goes into the HDMI port of the LCD screen and the other one will go right into the Raspberry Pi’s HDMI port. This set up does not require any special drivers software nor does it require any format of post plugin set up.

Raspberry Pi comes with a tiny 15 pin ribbon cable connector that can support a Display Serial Interface or a DSI standard. This enables fast communication between an LCD screen and the chip.

You can use the Raspberry Pi 7 inch touchscreen display by connecting it with the Raspberry Pi board. All you need to do is to first attach the raspberry pi to the back of the display screen using standoffs and screws that come with the kit.

Now connect the Pi board to the ribbon cable and the display control board. Note the ribbon cable pin orientation is proper or not. After this, carefully release the tabs on both sides of the socket so that the cable slides all way. Now secure this by pressing down on the tabs till you hear a click of a lock. Make sure you are not forcing the cable to lock.

If not, you can simply connect a power supply to the control board and then connect a small micro USB cable in the control board’s USB port and the micro USB port of the Pi. This should power on the device. You are now done setting up the device and the screen and once the power flows, the device boots up.

If the screen does not automatically turn on when the power source is connected, you may have to connect an existing HDMI display for updating your Raspberry Pi board and then reboot the device.

The Raspberry Pi 7″ Touch Screen Display from the house of Raspberry has a great colour output of 800 x 400 pixels and its capacitive touch is multi-fingered up to 10 fingers. That and the fact that it is specifically built for Raspberry pi Boards by the Raspberry company makes it the best Raspberry Pi LCD screen for your DIY Raspberry pi kit.

While those were our picks, we are intrigued by your choices, thoughts and opinions. Did we miss out on anything? Or do you want us to add anything else to this list? If so or if you have any questions for us or about the products mentioned, feel free to write to us in the comments section below. Our product expert team will write back to you as soon as possible.

The digital currency market can be extremely volatile—sometimes moving 20% within a single day. And unlike the stock market, trades are executed 24x7 and 365 days a year. All of this means that keeping track of market momentum can be extremely important.

While you could download an app on your smartphone or visit various websites to check a particular cryptocurrency’s price, neither equal the convenience of an always on display. With a live ticker, price checks become as easy as glancing at a wristwatch or wall clock.

To build such a cryptocurrency price ticker, all you’ll need is a Raspberry Pi along with a small LCD display. The Pi is a surprisingly powerful computer that sips power and outputs virtually no heat or noise—perfect for our application.

A brand-new Raspberry Pi 4 will set you back a mere $35. If you don’t plan on running any other applications on it in the future, you could even get away with purchasing the Pi 3 for this guide. While you will sacrifice some performance overhead, the previous generation device can usually be picked up for less.

What cannot be used, however, is the Raspberry Pi Zero. As you’ll see in later sections of this guide, the ticker involves hooking up an external LCD display to the Pi via a serial interface. Most Pi Zero devices are not sold with pre-installed GPIO headers, so even just connecting the LCD display will require some tinkering and soldering first.

A 3.5-inch screen and case combo that connects to the Pi via the SPI interface. We recommend this 3.5-inch TFT Raspberry Pi display for the Pi 3 or this 3.5-inch Raspberry Pi 4 display for the Pi 4.

Since the Pi is sold at a razor thin margin, you’re expected to install your own storage device. That’s exactly where the microSD card you purchased earlier comes into play.

After completing the initial set up process, make sure the Pi is properly connected to your Wi-Fi network and displays the correct time in the top right hand corner. If either of these settings are configured incorrectly, delve into the Settings app and make the requisite changes. When you"re ready, shut down the Pi.

Disconnect the Pi from your monitor and connect it to the aforementioned 3.5 inch display instead. Since every screen is different, follow the manufacturer’s instructions on how to do this. It should just be a matter of lining up the pins on the screen and the Pi’s GPIO header.

Once the Pi has booted, click on the black rectangular icon to the top left of your screen. This will open up a terminal window where you can perform administrative tasks such as installing software and updating the system.

Upon rebooting, your Pi should automatically load the ticker software. From this point on, the prices and other relevant data for various cryptocurrencies will be displayed on-screen. To exit the program, all you need to do is hit Alt+F4 on a keyboard connected to the Pi.

By default, the ticker will only display a handful of the most popular cryptocurrencies currently being traded. Luckily, adding or removing cryptocurrencies from your new ticker is pretty straightforward.

HyperPixel 2.1 Round has all the great features of our other HyperPixels - crisp, brilliant IPS display, touchscreen, and high-speed DPI interface—it"s just rounder! You can use it with any Raspberry Pi with a 40 pin header* but it works particularly nicely with the Pi Zero footprint - we"ve designed it so you can mount a Zero neatly behind it, so you can"t see the Pi when you look at it from the front.

This version of HyperPixel would be great for custom interfaces and control panels - mounted on a wall it would make a really neat, minimalist smart home controller or a stylish "what"s playing" display for your sound system. Everything is pre-soldered and ready to go, just pop it onto your Pi, install our software, and away you go!

* Please note that standoffs and booster headers are not included with Hyperpixel Round - scroll down or check out the extras tabs for some links. You will need a booster header if you want to use Hyperpixel Round with a full size Pi!

HyperPixel 2.1 Round uses a high-speed DPI interface, allowing it to shift 5x more pixel data than the usual SPI interface that these small Pi displays normally use. It has a 60 FPS frame rate and a resolution of approximately 229 pixels per inch (480x480px) on its 2.1" display. The display can show 18-bits of colour (262,144 colours).

The touchscreen variant is capacitive touch, that"s more sensitive and responsive to touch than a resistive touch display, and it"s capable of multi-touch!**

Hyperpixel Round will work with any 40-pin version of the Pi, including Pi Zero and Pi Zero W. If you"re using it with a full-size Pi then you"ll need a booster header to raise it up over the Pi"s USB ports and extended standoffs if you"d like to bolt it in place. If you"re using a Pi Zero or Pi Zero W you won"t need a booster header, but we have some special short standoffs that will let you attach everything securely together in an extra slim package.

If you"re using standoffs to fasten your Hyperpixel and your Pi together, just screw them into the posts on the underside of the HyperPixel PCB and then secure with screws through the mounting holes on your Pi.

Please note: when installing HyperPixel 2.1 Round onto your Pi make sure not to press down on the screen surface. We recommend putting the screen face down on a soft surface and gently wiggling the Pi to mate with the extended header (or GPIO header). If you need to remove your Hyperpixel, take care not to pull on the edges of the glass display - it"s best to hold on to the rectangular PCB. As the glass edges of this display overhang the PCB they"re quite exposed, so it"s worth being extra careful with them.

With this version of HyperPixel, we"ve separated the display drivers and touch drivers which should hopefully make it easier to incorporate touch interfaces into your own programs. To download and install the display drivers:

Note that you"ll need another display, keyboard, and mouse to install the software, or you could do it remotely over SSH if you set your Pi up headlessly.

HyperPixel uses basically all of the GPIO pins o communicate with the Pi (including the standard I2C pins) so it"s not generally possible to use it with other HATs and devices that connect via the GPIO...

...but we have provided an alternate I2C interface broken out on the back that will let you use I2C devices (like sensor breakouts) at the same time as HyperPixel. There are instructions how to set this up in our Hyperpixel 4.0 tutorial (scroll down to the bottom).

Raspberry Pi OS Bullseye includes major changes to how DPI display drivers work - a quick hack to get the screen working (with some loss of rotation/touch functionality) is to comment out dtoverlay=vc4-kms-v3d in boot/config.txt. We"re working on full support for Bullseye, but if you"re after an easy, fully featured Hyperpixel experience you should probably stick with Buster for now:

raspberry pi lcd display tutorial pricelist

A number of people have used a Motorola Atrix Lapdock to add a screen and keyboard with trackpad to RasPi, in essence building a RasPi-based laptop computer. Lapdock is a very clever idea: you plug your Atrix smart phone into Lapdock and it gives you an 11.6" 1366 x 768 HDMI monitor with speakers, a keyboard with trackpad, two USB ports, and a large enough battery for roughly 5 hours of use. The smart phone acts as a motherboard with "good enough" performance. The advantage over a separate laptop or desktop computer is that you have one computing device so you don"t need to transfer files between your phone and your desk/laptop.

Unfortunately for Motorola, Lapdock was not successful (probably because of its US$500 list price) and Motorola discontinued it and sold remaining stock at deep discounts, with many units selling for US$50-100. This makes it a very attractive way to add a modest size HDMI screen to RasPi, with a keyboard/trackpad and rechargeable battery power thrown in for free.

Lapdock has two connectors that plug into an Atrix phone: a Micro HDMI D plug for carrying video and sound, and a Micro USB plug for charging the phone and connecting to the Lapdock"s internal USB hub, which talks to the Lapdock keyboard, trackpad, and two USB ports. With suitable cables and adapters, these two plugs can be connected to RasPi"s full-size HDMI connector and one of RasPi"s full-size USB A ports.

The RasPi forum has a long thread on Lapdock with many useful suggestions, photos, and links: I made a Raspberry PI Laptop. There"s also a good "blog entry at element14 with photos and suggestions of where to get cables and adapters: Raspberry Pi Laptop. TechRepublic has a tear-down article with photos of Lapdock internal components here: Cracking Open the Motorola Droid Bionic Lapdock. Paul Mano has a wealth of photos of Lapdock innards at Motorola Atrix Lapdock mod projects.

Lapdock uses the HDMI plug to tell if a phone is plugged in by seeing if the HDMI DDC/CEC ground pin is pulled low. If it"s not, Lapdock is powered off. As soon as you plug in a phone or RasPi, all the grounds short together and Lapdock powers itself on. However, it only does this if the HDMI cable actually connects the DDC/CEC ground line. Many cheap HDMI cables do not include the individual ground lines, and rely on a foil shield connected to the outer shells on both ends. Such a cable will not work with an unmodified Lapdock. There is a detailed "blog entry on the subject at element14: Raspberry Pi Lapdock HDMI cable work-around. The "blog describes a side-benefit of this feature: you can add a small power switch to Lapdock so you can leave RasPi attached all the time without draining the battery.

The Lapdock Micro USB plug is the upstream port of Lapdock"s internal USB hub, and connects to one of RasPi"s full-size USB ports. Lapdock is not USB compliant since it provides upstream power on its Vbus pin. Lapdock uses this to charge the Atrix phone. You can use this feature to power RasPi if you have a newer RasPi. The original RasPi rev 1 has 140 mA polyfuses F1 and F2 to protect the USB ports, which are too small for powering RasPi using upstream power. Newer RasPis replace F1 and F2 with zero Ohm jumpers or eliminate them entirely, which allows Lapdock to provide power. If you don"t mind modifying your original RasPi, you can add shorting jumpers over F1 and F2 or replace them with higher-current fuses.

What gets powered on depends on whether Lapdock is open or closed. If it"s open, the screen and all Lapdock USB ports are powered. If you close Lapdock, the screen and full-size USB ports are powered down, but the Micro USB still provides upstream power. This is for charging an Atrix phone. When you open or close Lapdock, the Micro USB power switches off for about a second so if your RasPi is connected it will reboot and you may have a corrupted file system. There"s discussion about this at the RasPi forum link, and someone has used a supercapacitor to work around the problem: Raspberry Pi lapdock tricks.

When you do not connect a HDMI monitor, the GPU in the PI will simply rescale (http://en.wikipedia.org/wiki/Image_scaling) anything that would have appeared on the HDMI screen to a resolution suitable for the TV standard chosen, (PAL or NTSC) and outputs it as a composite video signal.

The Broadcom BCM2835 only provides HDMI output and composite output. RGB and other signals needed by RGB, S-VIDEO or VGA connectors are however not provided, and the R-PI also isn"t designed to power an unpowered converter box.

Note that any conversion hardware that converts HDMI/DVI-D signals to VGA (or DVI-A) signals may come with either an external PSU, or expects power can be drawn from the HDMI port. In the latter case the device may initially appear to work, but there will be a problem, as the HDMI specs only provide in a maximum of 50mA (@ 5 Volt) from the HDMI port, but all of these adapters try to draw much more, up-to 500mA, in case of the R-PI there is a limit of 200mA that can be drawn safely, as 200mA is the limit for the BAT54 diode (D1) on the board. Any HDMI to VGA adapter without external PSU might work for a time, but then burn out D1, therefore Do not use HDMI converters powered by the HDMI port!

The solution is to either only use externally powered converters, or to replace D1 with a sturdier version, such as the PMEG2010AET, and to replace the power input fuse F3 with a higher rated one, as the current one is only 700mA, and the adapter may use 400mA itself. Also notice that the R-PI"s power supply also must be able to deliver the extra current.

Alternatively, it may be possible to design an expansion board that plugs into the LCD headers on the R.Pi. Here is something similar for Beagleboard:

The schematics for apples iPhone 3gs and 4g suggest they speak DSI, thus they can probably be connected directly. The older iPhones use a "Mobile Pixel Link" connection from National Semiconductor. The 3GS panel (480×320) goes as low as US $14.88, while the 4G one (960×640, possibly the LG LH350WS1-SD01, with specifications) can be had for US $17.99 or as low as US $14.28. The connectors used might be an issue, but this connector might fit. Additional circuitry might be necessary to provide the display with required 1.8V and 5.7V for operation, and an even higher voltage for the backlight.

The Raspberry Pi provides one clock lane and two data lanes on the S2 connector, as can be read from the schematics. It is currently unknown whether this is enough to drive the iPhone 4G screen, as that screen seems be driven with three data lanes in its original application.

I2C/SPI ADC can be used to interface 4 pin resistive Touch Screens, For example STMPE812A. Texas Instruments has a solution for 4 or 8 wire touchscreens using their rather cheap MSP4309.

Parallel interface displays can be found in many sizes, usually up to 7" and more. Parallel interfaces are usually 8 or 16-bits wide (sometimes 18 or 24-bit wide), plus some control-lines. The Raspberry Pi P1-connector does not contain enough GPIOs for 16-bit wide parallel displays, but this could be solved by borrowing some GPIOs from the CSI-connector or from P5 (on newer Raspberry Pis). Alternatively, some additional electronics (e.g. shift-registers or a CPLD) can be used, which could also improve the framerate or lower the CPU-load.

After I posted my Raspberry Pi server room rack temperature monitor project, I received many questions on how to integrate LCD displays with the Pi. This video is the first in a series of tutorials:

R is the resistor value in ohms and Vdd is the supply voltage. VLED and ILED are the typical LED voltage and current respectively as specified in the LCD display datasheet. Even if you display supports 5 V you might want to add a resistor or variable resistor to control the brightness. The same holds true for the contrast pin. I normally use variable resistors for both (see below).

I’ll demonstrate 2 different Python modules for controlling the LCD display. The first is a modified version of lcd.py by Raspberry Pi Spy which can be downloaded below.

You can use any GPIO pins for the LCD RS, E, & D1 – D4. The GPIO to LCD pin mappings are specified in the LCD.py file. If you change from the default below then you have to update the file with your new selections.

Here is some sample code (updated 4/23/16) to demonstrate the Adafruit library. As with the LCD.py module, you can use any GPIO pins. You specify the GPIO to LCD pin mappings when you instantiate the Adafruit_CharLCD class. Please note that super-user privileges are no longer required for GPIO access with the latest version of Raspbian

A potentiometer can be added to the LCD display C pin to control the contrast. The pin is connected to the wiper of the pot which is usually the middle pin. One of the outside pins is connected to ground and the other to Vcc. It doesn’t matter which outside pin goes to Vcc or ground because the pot is acting as a voltage divider either way. As the dial is turned the wiper’s pin voltage will vary from 0 to 5 V and this will cause the contrast to change. 10 KΩ is a good value for the pot. This same wiring will also work to control the LCD display brightness. Instead of of the contrast pin, the wiper would be connected to the LED back light anode. Most LCD display back lights will tolerate 5 V but please double check so you don’t damage the LED. You can alter the 0 – 5 V range by adding a resistor in series with one of the outside pins. This can help fine tune the amount of range provided by the pot. You can use a multimeter to measure the voltage on the wiper and determine how different resistors affect the range. Here is a simple schematic:

The Adafruit IP clock example from the video is no longer compatible with the latest version of the Adafruit LCD_Char library. Here is an updated version of the IP clock program. Please note that sudo is no longer necessary to run the program with the latest version of Raspbian, but you still need the shebang line and chmod +x to give the file executable permissions, if you run it from the command line.

The Adafruit_Python_CharLCD library has been deprecated since this tutorial was released in 2014. Therefore, I’m including an example using the newer Adafruit_CircuitPython_CharLCD library which can run on both the Raspberry Pi and other CircuitPython compatible boards. I have several CircuitPython tutorials. The library can easily be installed using pip:

It is possible to connect multiple LCD displays to a Raspberry Pi. Normally I’d recommend using an I²C display as discussed in my Using an I²C LCD Display with a Raspberry Pi tutorial because the wiring is less complicated. However, LCD displays can be daisy chained in 4 bit mode. The second display is connected to the existing GPIO pins for RS and D1 – D4, but each display must have a unique GPIO pin for Enable.

Raspberry Pi boards are tiny, incredibly versatile computers that have been put to an increasing number of practical, fun, and diverse uses by hobbyists. This exceptional flexibility has only been increased over the years by manufacturers coming out with a plethora of add-ons like

All of this popularity created strong demand even before the world"s supply chain was struck by the impacts of the COVID-19 pandemic and the subsequent chip shortages, the effects of which linger to this day. Matters were made even worse by the increasing interest of hobbyists with unexpected free time over the pandemic scooping up boards for use in their various projects.

While there may be hope on the horizon for easing these supply constraints, the task of finding an in-stock Raspberry Pi board can be frustrating and sometimes, ahem, fruitless. To help you track down these elusive mini PCs, we"ve created this handy guide.

If you"re mostly interested in the best retail sites to check for a reasonably priced Raspberry Pi boards, feel free to scroll through and check them out. But, if you"re looking for more in-depth coverage of what each alternative has to offer, we"ve included additional info on each and which are best for specific types of projects.

This latest main-line generation from the Raspberry Pi Project includes the Raspberry Pi 4 with 1GB to 8GB of onboard RAM as well as the Pi 400 and Pi Pico, which we"ll cover in separate sections below. As the latest model, the Pi 4 is among the hardest to find. It launched about two years ago with an MSRP of $35-$70, depending on the amount of RAM included.

Unfortunately, acquiring a Raspberry Pi 4 as a bare board right now will require a lot of patience, a deep pocket book, or both. The original price range has been impacted by price increases at the Raspberry Pi Project (brought on by increasing chip costs) as well as resellers attempting to exploit the scarcity to hike prices up.

While the Raspberry Pi Project does price control the cost of the units at authorized merchants (to about $75 at the moment), those sellers frequently see their stock emptied within minutes of posting new availability, especially now that bots are being applied to the task of buying out boards for later scalping. Reliable outlets like Adafruit (one of the earliest and most trusted sources for Rasperry Pi hardware) have put buying limits and verification technologies in place to prevent being wiped out by bots. But, even then, enough legitimate, human customers remain to drain supplies rapidly.

If you need a Pi 4 board immediately, expect to pay anywhere between $125 and $175, depending on the RAM included. If you must have a main-line Pi 4 board, but simply can"t stomach that level of price gouging, I"d recommend signing up for email notifications at Adafruit or Micro Center. Both companies offer retail prices far closer, if not in line with, the original MSRPs for Pi 4 boards at various memory levels.

If you choose to purchase your Raspberry Pi 4 from a seller not listed in this article, please make sure it is a reputable, well-reviewed retailer. The scarcity of Pi boards has led to an explosion in scams surrounding them. If a seller"s price for the board you"re seeking seem too good to be true, it probably is. Try to have patience, or save up some extra cash, and purchase your board through a reputable retailer, or at least from a reseller offering the product via a website that provides buyer protections in the event your order is not delivered, or is not as described.

The Raspberry Pi 400 is essentially a modified 4GB model of the Raspberry Pi 4 board with additional cooling which makes it safe for the unit"s CPU to run at a slightly different clock speed. Rather than being sold as a bare board, the entire Pi 4 is loaded into a compact 60% keyboard with its included I/O ports on the keyboard"s top edge.

The inclusion of the keyboard may make this solution less than ideal for many applications one would want a Raspberry Pi 4 unit for. However, many other uses (gaming, text editing, media server applications, etc.) would have required the connection of a keyboard for control or text entry purposes anyway. Not only does the Pi 400 mean you don"t have to add an external peripheral for this purpose, but its unique supply means it also tends to be in stock for MSRP slightly more often than its bare-board cousins.

The Pi 400 is also commonly offered as part of kits, frequently for the same price as the unit itself. The Adafruit option below includes a microSD card, data cable, power supply, mouse, and a beginner"s guide. You may still be looking at spending over $100 on it, but if you calculate in the cost of a discrete keyboard, that price might sting a bit less.

The Pi Pico can also be expanded via a variety of accessories designed to work with its headers, as well as via custom-designed breadboards, and various other add-ons capable of increasing its versatility. A newer version,the Raspberry Pi Pico W, even includes built-in wireless connectivity now.

It"s also, by far, the cheapest option available right now, and is generally more readily available at or around its MSRP. Even at double the original $4 price point for the wired model or $6 price point for the Pico W, it"s still an excellent value for the right project.

The Raspberry Pi Zero line has been around since 2015 to offer a lower-cost option for users that don"t need the full computing power and I/O port selection of the full-sized Pi. Over the years, it"s been revised to add improved processors, new wireless connectivity options, and other improvements.

The latest version in the line is the Pi Zero 2 W. Launched in late 2021, this model includes a system in a package (SiP) design based on the previous-generation Pi 3. This means it"s very close in capability (for the right project) to the Pi 4, and is often more easily acquired due to being a slightly less versatile option than its top-of-the-line siblings.

You should definitely check to see if the project you have in mind can be handled by the less powerful Pi Zero 2 W. But, if it can, you can generally purchase the units for something closer to their original MSRP than you"ll ever find a Pi 4. It may be the most cost-effective and readily available option for the right buyer.

One of the most well-liked entries on our Best Raspberry Pi alternatives list, the NDVIDIA Jetson Nano aims to fill many of the same roles as the Raspberry Pi 4. It provides a similar set of I/O ports, 2GB of RAM, and a fairly identical set of extremely diverse applications.

While its close resemblance to the Raspberry Pi 4 means the Jetson Nano is also being bought up at an alarming rate, it unfortunately had a starting price that was already in excess of what the Pi 4"s inflated pricing was. This means you can expect to pay several hundred dollars for it today. Of course, given the scarcity of the Pi 4, it may just be the only option for some hobbyists that need a solution right now. Just make sure whatever plans you have for the NVIDIA Jetson Nano are compatible with its included chipset and I/O.

As I hinted at in the opening, there"s hope for the first time in a few years that supply constraints may be easing. This is because of blog post made by Raspberry Pi chief Eben Upton in which he predicted that "supplies in Q2 [2023] should recover to pre-pandemic levels." Going on to deliver the long-awaited news that "supply will be "unlimited" in the second half of 2023."

You might expect there to be an updated model waiting in the wings since the Pi 4 is the longest serving flagship board in the series" history. However, it doesn"t look like that will be the case any time soon. Eben Upton has confirmed that his team is currently focused on recovering from the supply chain shortages for their existing models, rather than creating entirely new SKUs.

Upton said in a late 2022 interview that 2023 will be a "recovery year," and "don"t expect a Pi 5 next year." Of course things could change, and new revisions of existing Pi 4 variants could make an appearance. But, it looks like we"ll have to wait until at least 2024 for a Pi 5 to make its debut.

If you"re aiming for something simple, like teaching kids about coding and electronics, something as cheap as the Pi Pico is more than enough to create many fun and educational projects ranging from wearable devices to simple games and even interactive PC peripherals.

If you want something a bit more complex but still affordable, consider the Pi Zero family, which offers a much wider array of add-ons such as digital and LCD displays, wireless communication modules, speakers, microphones, and more.

If you think this is likely to be a long-term hobby for you or the intended recipient, it might be worth going through the extra effort or cost of buying a full-on Pi 4. This will offer the maximum amount of power, versatility, and flexibility to grow alongside the user as they become more experienced and adventurous. Everything from basic smart-home devices, to remote camera setups, and even retro gaming consoles can be created with just a bit of extra hardware connected to the Pi 4.

The answer is a very qualified yes. While the I/O ports of a Pi 4 and its onboard processor can indeed replace a PC for basic computing needs, it does not have anywhere near the power required for more advanced operations.

However, more advanced things like video editing, modern gaming, and advanced productivity tasks will tend to run into some walls. Whether those limitations come from a lack of computing power, incompatible peripherals, or a lack of required I/O, the Pi 4 cannot replace a PC in all situations. But, it can get pretty dang close in a shocking number of them.
