pi tft lcd 3.5 manufacturer

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.

The 3.5 inch RPI lcd display TFT Capacitive Touch Screen is a display module can be applied to Raspberry pi 3 B+ Pi Zero etc. It can be used as raspberry pi x window display terminals.

The RPI LCD Display TFT Capacity Touch Screen Modules used 28 pins out of raspberry pi 40 pin. When installing the module attention to align the first leg of the raspberry pi and LCD module.

It is the cutest, little display for the Raspberry Pi. It features a 3.5″ display with 480×320 16-bit color pixels and a resistive touch overlay. It’s designed to fit nicely not only to the Pi Model A or B but also works perfectly fine with the Model B+/2B/3B.

So, the only place to buy raspberry pi addons where I live is an aftermarket which is not very well documented. I recently purchased a 3.5 inch resistive tft screen, with no information about the manufacturer, for about $25. I"m trying to hook it up to my Pi 2 which is running a fresh install of Raspbian Jesse, using this tutorial and a few blog posts. The problem is that I don"t know the name of the device or the manufacturer, so I cannot complete the tutorial.

Is this not the cutest, little display for the Raspberry Pi? It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay so it is slightly larger than the Raspberry Pi board, which is perfect to cover it. The plate uses a high-speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video, etc. Best of all it plugs right on top nicely covering the Raspberry Pi board. Single power from Raspberry Pi is sufficient to operate the screen. As it uses the SPI and Power pin from Raspberry Pi"s GPIO, it is nicely stacked on the RPi board. We also carry the perfect case/enclosure for Raspberry Pi 3B/3B+ and also 4B to be used with this LCD.

There’s a lot of interest in these little Pi-shaped screens, but there doesn’t seem to be one that is truly “plug n’ play” working straight out of the box.

I may have found something that makes it a little closer to that true plug n’play goal – the 3.5″ TFT screen from NeoSec Solutions. They offer a similar product to the PiTFT however overall I’ve found it a lot easier to set up.

It’s hard to look at any small touch screen for the Pi without comparing it to the ever popular PiTFT – so rather than pretend to not be comparing it – this review will face the boards off against each other and see what’s the best screen in each category. I don’t normally do this, but it just makes sense in this scenario.

The NeoSec 3.5″ TFT is a small touchscreen LCD display that pushes on to your Raspberry Pi (Model A/B) via the GPIO pins. The screen makes use of nearly all available space above the Pi, allowing a decent 480×320 resolution. It comes packaged in a small clip-top box with everything inside.

The GPIO is accessible via the extra PCB tab below the screen, allowing you to connect any kind of header you want (or none at all). It looks as though this could be cut/snapped off if required, as there are a number of droll holes creating the break for you. It’s subtle and out of the way:

The image file is the big winner here for me. I put the image on to a blank SD card (8Gb as it didn’t fit my 4Gb), turned on the Pi, and it was ready to go. No messing around, no code – just a working screen out of the box. Compare that to the hassle of some other TFT screens for the Pi and you’ll see why I’m so impressed with this.

The screen itself is nice and bright, with rich blacks, and that 480×320 resolution keeping the font to a nice size to see as much as possible on screen. I love the size of this screen, and the way it covers the Pi completely. There’s also very little blank space on the screen itself.

I guess it’s hard to keep us happy – we all want the biggest screen on our Pi, but to achieve that you need to remove the PCB area. A tough balance to strike.

Whilst I dont normally compare products when writing a review, theres an obvious competitor that you cant help but compare to when you see other small Raspberry Pi screens…so this review will focus on the pros/cons of the NeoSec 3.5″ TFT compared to the 2.8″ PiTFT from Adafruit.

Although these screens are different in features and size, they’re suitable for comparison in terms of “Pi sized touchscreen vs Pi sized touchscreen”.

The AdaFruit screen rolls up at $34.95 – including the screen only (no buttons). You also have to assemble this screen, including soldering the main GPIO connector and taping down the screen element.

Verdict: NeoSec wins this one. Considering the extras you get with it, I personally think it’s a better deal for a ‘screen on Pi’ solution. (and the basic $25 package is clearly much cheaper)

The PiTFT requires assembly, including GPIO and button soldering, and taping the screen to the PCB. That tape isn’t very sticky at all so you’ll probably need to get your own – I used No Nails tape.

Verdict: I think self-assembly can be a good learning experience, but considering how many people I’ve heard complaining of the difficulty of assembling the PiTFT, NeoSec wins this one.

The NeoSec weighs in at a more comfortable 3.5″ and a clearer 480×320 resolution. The 3.5″ screen covers more of the Pi, which I think looks much smarter. That extra screen space does come at a price, which is the slightly more delicate feel it has, and no mounting holes for support screws like the PiTFT:

The font on the NeoSec screen seems smaller yet clearer, allowing more on screen, but there may be a way to match this on the PiTFT that I haven’t discovered yet:

Verdict: You can’t argue with the bigger screen of the NeoSec, and it does seem to have much better colour and clarity. It seems an easy decision when considering these two as being in the same product market – however the PiTFT certainly feels more sturdy with that PCB surround. I’m going for the NeoSec here – but it is tight.

The PiTFT has holes around it to use nylon screws as a screen support. It also has PCB area around the screen acting as a bit of protection. The PCB covers the entire underside of the screen, ensuring no light comes out of the back.

The NeoSec screen doesnt have any support holes, and has no PCB area around the screen (but its a bigger screen, which is more important in my eyes). I can’t see the NeoSec doing well on a Model A without that Ethernet port holding it up. The NeoSec’s PCB doesn’t cover the rear of the screen either, so light comes out on to your Pi.

Verdict: The PiTFT wins this one, it feels much more secure, and I’m pretty sure light bleed from the back isn’t meant to happen – even if it does look cool.

The PiTFT has an optional upside-down connector to attach a belt to breakout to a breadboard. I don’t like the whole belt thing, it feels a bit too 90’s computing for me, and the upside down back to front thing makes it hard to do something different like add a regular GPIO header.

The NeoSec is a little more traditional with the GPIO, and simply gives you a mirror of the GPIO next to the screen. This is good if you want a simple prototyping access, but perhaps not as ideal if you just want a screen, as it does stick out. It looks as though it can be removed as drill holes indicate an easy option to cut or snap it off.

Verdict: Tie – it all depends on what you want the screen for. The PiTFT may be better for breakout projects, whilst breaking off the GPIO tab on the NeoSec may be better for those looking for a simple screen solution.

The PiTFT comes ready to fit 4 tactile buttons to, however these need to be purchased and fitted separately. The blue PCB of the Adafruit board is attractive when compared to traditional colours.

The NeoSec on the other hand, was much easier to get going. I simply installed the image provided on the DVD supplied (no long download required) and it worked straight away. You have to tweak a couple of settings if you’re using a Rev1 board, but with a Model A/B it’s real easy. You also don’t seem to need to push things to the display using code – it picks up everything as default from what I’ve tested.

I thought I’d add a final section on support, as I had a few questions while writing this review, and previously had questions on the PiTFT when I first used it.

The PiTFT benefits from the massive following and fan base that Adafruit command. Their forums are full of information, and generally a lot of people buy their products, so most people have had the issue and written about it on blogs and forums.

The NeoSec screen doesn’t have that massive following that AdaFruit does, so finding information already out there can be difficult. Fortunately NeoSec counteract this by providing excellent personal support by email and also regularly on the Raspberry Pi forum.

It’s important to stress “personal choice” here. Everyone will have different uses for a Pi-sized screen, so a lot of us will probably sway one way or another purely based on the features and functionality we need.

Sure the PiTFT has that sexy blue AdaFruit styling we all love, and the screen feels more secure and has an overall better ‘feel’ to it (plus those optional buttons are very cool), but the setup involved many hours of my life that I’m unlikely to get a refund for.

The other reason is purely the size of the screen – the 3.5″ full-size unit looks so much smarter than a 2.8″ surrounded by PCB – and it’s simply ‘more screen’ – that’s why we bought it in the first place right?

The extra size and resolution gives a much better picture too – the colour and clarity are beautiful. Add to that the extras such as the pen and the touchpad, and for a extra few dollars the NeoSec feels like the better buy.

Raspberry Pi is a Palm Size computer that comes in very handy when prototyping stuff that requires high computational power. It is being extensively used for IOT hardware development and robotics application and much more memory hunger applications. In most of the projects involving the Pi it would be extremely useful if the Pi had a display through which we can monitor the vitals of our project.

The pi itself has a HDMI output which can be directly connected to a Monitor, but in projects where space is a constrain we need smaller displays. So in this tutorial we will learn how we can interface the popular 3.5 inch Touch Screen TFT LCD screen from waveshare with Raspberry pi. At the end of this tutorial you will have a fully functional LCD display with touch screen on top of your Pi ready to be used for your future projects.

It is assumed that your Raspberry Pi is already flashed with an operating system and is able to connect to the internet. If not, follow the Getting started with Raspberry Pi tutorial before proceeding.

It is also assumed that you have access to the terminal window of your raspberry pi. In this tutorial we will be using Putty in SSH mode to connect to the Raspberry Pi. You can use any method but you should somehow be able to have access to your Pi’s terminal window.

Connecting your 3.5” TFT LCD screen with Raspberry pi is a cake walk. The LCD has a strip of female header pins which will fit snug into the male header pins. You just have to align the pins and press the LCD on top of the Pi to make the connection. Once fixed properly you Pi and LCD will look something like this below. Note that I have used a casing for my Pi so ignore the white box.

For people who are curious to know what these pins are! It is used to establish a SPI communication between the Raspberry Pi and LCD and also to power the LCD from the 5V and 3.3V pin of the raspberry Pi. Apart from that it also has some pins dedicated for the touch screen to work. Totally there are 26 pins, the symbol and description of the pins are shown below

Now, after connecting the LCD to PI, power the PI and you will see a blank white screen on the LCD. This is because there are no drivers installed on our PI to use the connected LCD. So let us open the terminal window of Pi and start making the necessary changes. Again, I am using putty to connect to my Pi you can use your convenient method.

Step 2: Navigate to Boot Options -> Desktop/CLI and select option B4 Desktop Autologin Desktop GUI, automatically logged in as ‘pi’ user as highlighted in below image. This will make the PI to login automatically from next boot without the user entering the password.

Step 3: Now again navigate to interfacing options and enable SPI as show in the image below. We have to enable the SPI interface because as we discussed the LCD and PI communicates through SPI protocol

Step 4: Click on this waveshare driver link to download the driver as a ZIP file. Then move the ZIP file to you PI OS. I used Filezilla to do this, but you can also use a pen drive and simple copy paste work.  Mine was placed in the path /home/pi.

Step 7: Now use the below command to restart your Pi. This will automatically end the terminal window. When the PI restarts you should notice the LCD display also showing the boot information and finally the desktop will appear as shown below.

You can also watch the video below to check how the LCD is connected and how it responds to touch. I am pretty much satisfied with its default accuracy so I am not going to do any calibration. But if you are interested you can view the official wiki page from waveshare where they discuss how to calibrate and enable camera view on the LCD screen.

Hope you understood the tutorial and were successful in interfacing your LCD with PI and got it working. If otherwise state your problem in the comment section below or use the forums for more technical quires.

This small 3.5-inch touch screen module is designed especially for Raspberry Pi, using the latest Linux Core system. This is ideal for DIY anywhere, anytime and does not require any separate power source or case to hold it. The module sits right on top of Pi. The screen also comes with a stylus to interact with the small screen.
