Raspberry Pi OS provides touchscreen drivers with support for ten-finger touch and an on-screen keyboard, giving you full functionality without the need to connect a keyboard or mouse.

The 800 x 480 display connects to Raspberry Pi via an adapter board that handles power and signal conversion. Only two connections to your Raspberry Pi are required: power from the GPIO port, and a ribbon cable that connects to the DSI port on all Raspberry Pi computers except for the Raspberry Pi Zero line.

Hi to all, I"m a new user, I have a Raspberry Model B and I bought a 7 Inch Capacitive Touch Screen LCD(C) 1024x600 HDMI (Makibes). This TouchScreen is connected to the Raspberry through an HDMI and a USB cables.

Basically, my problem is that: when I power on the backlight switch on the TouchScreen, the Raspberry stops (activity leds also stop) and the Raspberry freezes in few minutes. This occurs just when I power on the backlight on the LCD (and obviously I need it to use the LCD). If I let the backlight down, then it keeps regularly working.

The only way to use it seems to be using a separate power supply for the LCD, but I couldn"t connect it via USB to the Raspberry, so I couldn"t use the touch function: it acts just like a monitor.

However, I was reading the list you provided, and I read which are the ones without the polyfuses, but maybe you forgot to write down which are the ones with the polyfuses...

It appears that you are unable to get enough current into the RPi to power the RPi and the USB powered screen. That could be because your power supply is too weak and/or because the polyfuse on the micro-USB power input is tripping. A beefier PSU can overcome the former but not the latter. A powered USB hub is an easy solution to the latter. More difficult would be to connect an adequate PSU to the 5 volt power pins on the GPIO header. But that runs the risk of damaging (even fatally) the RPi if you get the connections wrong.

i asked which model of RPi because the B+, 2B and 3B are able to supply substantially more current to the USB ports than the earlier models. The lack of polyfuses on the USB ports of your B is not the problem.

So, talking about the fact that the B+, 2B and 3B are able to supply substantially more current to the USB ports than the earlier models... is that related to the option in the /boot/config.txt with two values (0 and 1) to give 600mA or 1200mA to the USB port?

Today I was able to try with another bigger PSU (2,4 A), but nothing new happened. I will try a 3 A in the next days but I don"t think it will solve anything.

After that, I tried also with a powered USB HUB. When the HUB isn"t powered I get a similar problem on the Raspberry (getting it freezed). When the HUB is powered, the monitor seems to keep to be alive together with the Raspberry.

The only thing I have to be careful is to avoid powering off the HUB, because the Raspberry get freezed, or doesn"t recognize the touch functionalities of the LCD.

Just a question: the seller told me that I have the first version of a Raspberry, also if I run the cat /proc/cpuinfo command getting a result like this:

Basically I found other two RPI (same revision of mine: 2708), and I saw that they work flawlessly with the LCD monitor, without the problems that I"m experiencing... The only difference is that the board of my RPI is made in China, while my friends have RPIs made in UK

I bought this more for the screen itself, not really concerned about the touch part, which I just thought was a nice bonus. The case was also a nice boon as well, which really helps to drive the value of this purchase.

Going over the quality of everything, the case isn"t bad. It"s nothing fancy, but for what it is it"s built well and everything fit together nicely. I had no trouble putting it all together, and its design happens to make it more convenient for me. This will certainly not protect the pi from dust or really anything else; It"s really just there to support the screen. Speaking of which, the screen is also built quite nicely. It"s a fairly good screen but unlike my IPS monitors, the backlight tends to reduce quality significantly when not viewed straight-on. This was somewhat disappointing but not entirely surprising. It"s not exactly practical to view the screen from 178 degrees but one reason I was attracted to this was because I wanted to be able to place this on a table and have no discoloration when viewed from a reasonable angle. For the most part, it"s fine, just not quite as good as I was hoping. Worth noting, it comes with some heatsinks and a fan. I wanted to keep the ones I had before but because they were so high-profile, they would get in the way of the included fan. I didn"t exactly feel comfortable omitting the fan, so I installed everything using the kit. So far it has not been an issue.

Depending on what you want to do with this screen, setup can be really simple or painful. If you set it up per their recommendations, I"m sure it all works fairly well, provided you are expecting to use this on a Raspberry Pi with the desktop enabled. I tried it briefly and it works alright but, to be honest, I am not sure why I would want to use a Raspberry Pi, even a 4, for the desktop experience. It"s impressive for the price and the size, but your smart phone, tablet, laptop or desktop computer will offer a far better experience than what this can offer. What I expected was that this little screen would basically be a tiny TV with a small resolution, but this isn"t exactly the case. The reason for this is that this screen is not 16:9, it"s 9:16. To clarify, this is just a little monitor with a HDMI input and a 3.5mm jack output, so I expected that with power supplied it would function just like any display would. My PC, however, did not recognize it at all, and the Pi is confused by it as well. You need to add in specific display settings into the Pi"s configuration file in order for it to work. Once it does, any apps designed for a landscape screen will not work well as this is in portrait. Surprisingly, the Raspberry Pi does not have a great workaround for this. If you intend to use Retropie, the drivers that allow the touch screen to allow touch, and to rotate, will not work. There are some workarounds for this and I suggest researching into how to set up Retropie as a vertical cabinet. Fortunately, the Retropie default interface works alright in portrait and games can be specifically rotated. Because the case"s design, you can also set it easily in portrait or landscape positions on its side. This was probably not the intent behind their design but it works nonetheless.

Last thing worth mentioning, you might wonder why you would want to use the 3.5mm jack on the screen instead of the one already available on the Pi4. I tried both and the one on the screen is significantly boosted. It does, however, seem to introduce a clicking sound into the audio sometimes. It"s noticeable and not really worth the added volume. I suspect this is a decent feature if you intend to plug this into something other than the Pi4 but otherwise it"s just another option for audio you can choose to use or not. With some work, it might be possible to eliminate the audio issue.

Firstly, as many of you may have found out, the manufacture screwed up and designed this thing UP SIDE DOWN. Which on a small screen you have to adjust you screen to project the image 180 degrees, but when you put it back on the big screen you have to adjust back.

Secondly, access to the SD Card requires unscrewing the case off the back of the Pi. The alternative is to find a microSD card extension ribbon, which will set you back about $13 depending on what manufacture doesn"t make you wait a month for that part to get stateside from China.

Lastly, there are NO compatible screws for this thing. NONE. M3 is too big. M2.5 is too small. And no matter what you pick, the thread length is too deep, too shallow, or the threads themselves don"t fit well with the hole you are trying to screw them in. You also have the risk of screwing the screws too deep that they could damage the LCD display.

There"s are a lot of design flaws with this thing. It was still better than the cheap 3D printed ones which had the flimsy legs that broke like twigs, and that was the appeal to buying this one. It needs to be redesigned.

There"s just one problem. Where are the screws? They didn"t come with my 7" screen when I bought it. They didn"t come with this box. And the last stand I had did come with screws but they are too long.

A good solution for those seeking for a bigger resolution display for Raspberry Pi. it can work as a computer monitor just like any other general HDMI screen too (compatible with win7,、win8,、win 10 computers).

Connect Raspberry pi HDMI port to LCD HDMI port using a HDMI cable. Then any Raspberry pi USB port to any of LCD micro usb port using a USB cable for power and touch signal.

No driver is needed for touch control, both for Raspberry Pi and windows computer. Multitouch works only on Windows. On Raspbian, only single touch works.

1. This LCD requires a good amount of current to work properly. So, while the LCD is connected to Raspberry Pi USB port (for power + touch), power up the Raspberry Pi with a good 5V 2A power adapter or power bank. Otherwise, Raspberry Pi won"t boot up.

2. This display works right out of the box with Windows computer. But to use this LCD with Raspberry Pi, you need to modify "config.txt" file of the SD card in which you"ve installed the Raspbian OS. Open"config.txt" using Wordpad and add the following lines at the end of it, save it.

3.This display works with latest Raspberry Pi OS (may not work with Raspbian Jessie or older). Works with ONLY Raspberry pi 4 (HDMI 0) and Raspberry pi 3B+.

This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems. When the LCD works on systems such as Raspberry Pi OS, the resolution must be set manually, otherwise, it will cause an abnormal display.

8) Connect the HDMI interface of the LCD to the HDMI interface of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds until the LCD displays normally.

On December 2, 2021, the Raspberry Pi OS was divided into two branches, the Buster branch, and the Bullseye branch. The Buster branch is a continuation of the old system and is more stable. The Bullseye branch added some new features, using open source libraries and new interfaces. Since the current Bullseye branch has just been released shortly, it is not stable yet. If you are an industrial user, it is strongly recommended to use the Buster branch.

If you use the Buster branch system, you can use it according to the above configuration. But if you are using the Bullseye branch system, you need to modify the default KMS driver to FKMS driver for displaying the system desktop normally.

Connect the Raspberry Pi camera to the CSI interface of the Raspberry Pi, power on the Raspberry Pi again, and after the system boots, execute the following command:

2. Input command xinput in the terminal, and check the touch ID of the main monitor. (There should be two IDs, you can touch displays to check which is the main one);

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

Raspberry Pis are still in short supply (but things are looking up in 2023), if you are lucky enough to grab a Raspberry Pi for as little as $5 (for the Raspberry Pi Zero) or more likely from $35 (for the Raspberry Pi 41GB), you"ll need a few extra products to make the most of it. There"s a whole world of accessories that help you make the most of the Raspberry Pi"s GPIO. These accessories have been around since the Raspberry Pi was released, when it had just 26 GPIO pins. Using special addon boards we can take advantage of the more recent Raspberry Pi"s 40 pin GPIO to control and interact with electronic components and create diverse projects such as robotics, machine learning and IoT and even our own home server.

As with any computer, you’ll need a way to enter data and a way to see the interface, which usually means getting a keyboard, a mouse and a monitor. However, you can opt for a headless Raspberry Pi install, which allows you to remote control the Pi from your PC. In that case, the minimum requirements are:microSD card of at least 8GB, but the best Raspberry Pi microSD cards have 32GB or more. When you first set up a Raspberry Pi, you need to “burn” the OS onto it by using a PC, another Raspberry Pi or even a phone with microSD card reader.Power supply:For the Raspberry Pi 4, you need a USB-C power source that provides at least 3 amps / 5 volts, but for other Raspberry Pis, you need a micro USB connection that offers at least 2.5 amps and the same 5 volts. Your power supply provides power to both the Pi and any attached HATs and USB devices, so always look for supplies that can provide a higher amperage at 5 volts as this will give you a little headroom to safely power your projects.

In addition, there are a number of accessory and add-on types that protect your Pi, add new features and make everything a lot more useful and fun. These include:Cases: The best Raspberry Pi cases give you style, functionality and durability.

Electronic parts: You can make great projects and have a lot of fun with motors, sensors, transistors and other bits and bobs. Just don"t forget your breadboard!

The top overall choice on our round-up of the best Raspberry Pi Cases, the Argon Neo combines great looks with plenty of flexibility and competent passive cooling. This mostly-aluminum (bottom is plastic) case for the Raspberry Pi 4 features a magnetic cover that slides off to provide access to the GPIO pins with enough clearance to attach a HAT, along with the ability to connect cables to the camera and display ports. The microSD card slot, USB and micro HDMI out ports are easy to access at all times.

It doesn"t come cheap, but the official Raspberry Pi High Quality camera offers the best image quality of any Pi camera by far, along with the ability to mount it on a tripod. The 12-MP camera doesn"t come with a lens, but supports any C or CS lens, which means you can choose from an entire ecosystem of lenses, with prices ranging from $16 up to $50 or more and a variety of focal lengths and F-stop settings. We tested the High Quality camera with two lenses, one designed for close up shots, the other for more distant, the image quality was a massive improvement over the standard Raspberry Pi camera.

If you need a Raspberry Pi camera, but don"t want to spend more than $50 on the high quality module and then have to bring your own lens, the official Raspberry Pi Camera Module V2 is the one to get. This 8-MP camera uses a Sony IMX219 sensor that gives it really solid image quality, records video at up 1080p, 30 fps and is a big improvement over the 5-MP OmniVision OV5647 that was in the V1 camera.

Whether you want to control your Raspberry Pi from the couch or you have it on a table and don"t want to waste space, getting one of the best wireless keyboards is a good idea. It"s particularly helpful to have a wireless keyboard with a pointing device so you don"t need to also drag around a mouse.

Lenovo"s ThinkPad TrackPoint Keyboard II is the best keyboard for Raspberry Pi thanks to its excellent key feel, multiple connectivity options and built-in TrackPoint pointing stick. The keyboard looks and types just like those on Lenovo"s ThinkPad line of business laptops, offering plenty of tactile feedback and a deep (for a non-mechanical), 1.8mm of key travel. The TrackPoint pointing stick sits between the G and H keys, allowing you to navigate around the Raspberry Pi"s desktop, without even lifting your hands off of the home row.

If you"re going to use a Raspberry Pi 4, you need a USB-C power supply that offers at least 3 amps of juice with a 5-volt output. We"ve found that the best USB-C laptop chargers are capable of delivering this kind of power (albeit often with 4.8 - 4.9 volts, which still works), but if you don"t have a powerful charger handy or need one just for your Pi, the official Raspberry Pi power supply is your best choice.

Rated for 5.1 volts at 3 amps, the official Raspberry Pi 4 power supply has good build quality and a nice design. Available in black or white, it"s a small rectangle, emblazoned with the Raspberry Pi logo and a strong, built-in Type-C cable that"s 59 inches (1.5m) long. Unlike some third-party competitors, it doesn"t come with an on / off switch, but it is compatible with cheap on / off adapters you can attach to the end. You may find competitors for a few dollars less, but the official Raspberry Pi 4 power supply is a sure thing.

The Raspberry Pi"s 40 GPIO pins are arguably its most important feature. Using these pins (see our GPIO pinout(opens in new tab)), you can attach an entire universe of electronics, including motors, sensors and lights. There"s a huge ecosystem of add-on boards, appropriately called HATs (hardware attached on top) that plug directly into the GPIO pins and matching the same layout as the Pi. These add on boards give you all kinds of added functionality, from LED light matrixes to touch screens and motor controllers for robotics projects.

If you"re using a Raspberry Pi 4, you definitely need some kind of cooling, whether it"s a heat sink, an aluminum with passive cooling built in or, best of all, a fan. The Pimoroni Fan Shim is powerful, easy-to-install and unobtrusive. You just push it down onto the left most side of your GPIO pin header and it does a fantastic job of cooling your Pi. You can even use a Pimoroni Fan Shim on a Raspberry Pi 4 that"s been overclocked all the way to 2.1 GHz, without seeing any throttling.

Unless you"ve specifically configured yours to boot from an SSD (see our article on How to Boot Raspberry Pi from USB), every Raspberry Pi uses a microSD card as its primary storage drive. We maintain a list of the Best microSD cards for Raspberry Pi and have chosen the 32GB Silicon Power 3D NAND card as the top choice.

Unless you"re hosting a media server or have a ridiculous amount of ROMS on a game emulator, a 32GB microSD card provides more than enough storage for Raspberry Pi OS and a ton of applications. The operating system and preloaded applications take up far less than 8GB by themselves.

Each of the Raspberry Pi"s 40 GPIO pins has a different function so it"s hard to keep track of which does what. For example, some of the pins provide I2C communication while others offer power and others are just for grounding. You can look at a GPIO pinout guide such as ours, but sometimes it"s just easier to put the list of functions right on top of the pins.

While most of the earlier Raspberry Pi models have a single, full-size HDMI port, the Raspberry Pi 4 has dual micro HDMI ports that can each output to a monitor at up to 4K resolution. While there"s a good chance you already have one or more HDMI cables lying around the house, most of us don"t have micro HDMI cables, because it"s a rarely used connector.

You can use your Raspberry Pi as a game emulator, a server or a desktop PC, but the real fun begins when you start connecting electronics to its GPIO pins. Of course, to even get started playing with GPIO connectors, you need some interesting things to connect to them such as lights, sensors and resistors (see resistor color codes).

The market is filled with electronics kits that come with a slew of LED lights, resistors, jumper cables, buttons and other bits and bobs you need to get started. Most importantly, all of these kits come with at least one breadboard, a white plastic surface filled with holes you can use to route and test circuits, no soldering required.

In order to write Raspberry Pi OS (or a different OS) to a microSD card, you"ll need some kind of microSD card reader that you can attach to your PC. Just about any make or model will do as long as it reads SDHC and SDXC cards and, preferably, connects via USB 3.0. I"ve been using the Jahovans X USB 3.0 card reader, which currently goes for $5.99, for almost a year now and it has worked really well.

TheRaspberry Pi 400’s big feature is that it is a Raspberry Pi 4 inside of a keyboard. This new layout introduced a challenge, the GPIO is now on the rear of the case, breaking compatibility with Raspberry Pi HATs but with the Flat HAT Hacker we can restore the functionality and delve into a rich world of first and third party add ons for robotics, science projects and good old blinking LEDs! In our review we found that the board is easy to install, and requires no additional software. If you have a Raspberry Pi 400, this is a no brainer purchase.
