» Makerfabs is Open Hardware, Arduino, Raspberry Pi, mbed, BeagleBone, IoT, Smart Home, etc, Related Products& Services Vendor for Makers and new Startups.

It is the cutest display for the Raspberry Pi. It features a 3.5" display with 480x320 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/4B.

*When working with Raspberry Pi 4, for the system image of Raspberry Pi after 2021-10-30, for example on Bullseye, please modify "dtoverlay = vc4-kms-v3d" to "dtoverlay = vc4-fkms-v3d" in the config file, otherwise it may fail to start. But on Buster, please comment out "dtoverlay = vc4-fkms-V3D" by adding #.

3.2 inch resistive touch screen TFT LCDwith 480 x 320 resolution designed to work directly with Raspberry Pi, Raspbian Image is provided in a DVD with this product. A Touch pen is also included for effective touch interface.It supports any revision of Raspberry Pi and it can be directly plugged on to the RPi board, combined with the portable power this module is a convenient Men-Machine interface for Raspberry Pi. As it supports Raspbian system it could enable your Pi to play videos and take photos on just a touch.

The touch screen LCD is ready with 320×480 resolution, 50 FPS (Frame per second). Resistive touch control is being supported by the Raspberry Pi OS or Raspbian (directly-pluggable). However, we will still need to install the driver for graphic display :)

However, there is a dedicated case/enclosure and a low-profile heatsink with a fan for this LCD to fit perfectly on the Raspberry Pi 4 Model B. The case has an opening for the LCD, and the low-profile heatsink with a fan keeps the Raspberry Pi 4 Model B protected and cool! You get a perfect console :) Don"t forget to remove the top lid/cover of the enclosure for the 3.5-inch LCD.

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

As we understand, Raspberry Pi 4 Model B delivers great performance and of course, more power will generate more heat as of all CPU :) So we need a way to install an additional heatsink to dissipate the extra heat. It will be better if we can have the option to add a cooling fan for active cooling. Well, this 3.5-inch touch screen LCD comes ready with the heatsink and cooling fan for you to use with the Raspberry Pi 4 Model B. it solves all the concerns.

The 3.5-inch touch screen uses the GPIO on the Raspberry Pi board, so it stretches out 2 pins as the power to supply the cooling fan on the low profile heatsink, and keep the Raspberry Pi board cool!

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

The Graphic driver is provided and can be downloaded for Raspberry Pi OS/Raspbian. It also supports Ubuntu and Kali Linux. Do follow the steps here: http://www.lcdwiki.com/MHS-3.5inch_RPi_Display

Note: Please use the recommended system for the touch screen. If another system is used, it may not have the touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with the touch screen.

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.

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.

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 screen features touchscreen functionality alongside a little directional touch pad attached via a belt cable. I’ve not seen this kind of thing in the market yet so this was a fresh approach, and comes in handy if you need precise mouse control (or you don’t want finger marks on your screen!). The touchscreen itself does also come with a pen, another nice little addition to the package.

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:

A buzzer is mounted to the rear of the screen which makes a sound every time you touch. I found this quite annoying, however NeoSec have told me that on the latest model this is optional, in case you don’t want the ‘beeps’:

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.

Providing an image file is nothing new, but this one actually works straight away unlike others. No configuration is required on the touch screen either – it comes accurate and ready to use.

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.

It does feel a little more delicate than some other screens I have seen, probably down to the fact that there’s no PCB area around it. There’s also nowhere to fit nylon screws or similar to help keep things steady – but I did a DIY job on this which isn’t difficult.

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”.

This NeoSec screen package comes in at $41 – that’s the screen, touchpad, pen and DVD. This is also pre-assembled. A basic package with just the screen is $25.

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.

It is hidden away though, which is nice and tidy if you’re not using it, and I’m pretty sure I’m the only person who hasn’t purchased a Cobbler belt breakout so maybe don’t listen to me!

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.

Verdict: The NeoSec clearly comes up trumps with more goodies – main winner here is the touchpad. Credit to Adafruit for the refreshing PCB colour though.

The image available on Adafruit’s site doesn’t seem to work properly (issues with the buttons), meaning you have to install a fresh copy of raspbian first, and then undertake the manual setup. Even that can be troublesome – so I wrote a blog guide on setting it up to help others.

The other niggle here is that it doesn’t become your default screen output, you have to use a bit of code here and there to push movies, images etc to the screen. All in all – a bit of a hair-pulling experience!

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 down side of a large company like this is that getting 1:1 email support quickly is unlikely due to the sheer number of requests they must receive (although I didn’t try this option, purely on the assumption it would take too long).

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.

If I could go back in time and purchase just one of these screens, knowing what I know now after having set up and played with both of these, I would personally go for the NeoSec screen.

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.

I thought it might have been down to my “Averageness”, but a lot of people have had the same problems. I usually enjoy a good challenge with my projects, but this one went on a bit too long for me – especially after spending that much money on it.

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.

The UCTRONICS 3.5 Inch touch screen is the same size as the standard Raspberry Pi model B/B+, and well-mates with the Raspberry Pi boards. With a tiny size, vivid image, and responsive touchscreen, it is definitely ideal for portable devices and multimedia projects. It is a great replacement for a heavy and bulky HDMI monitor, keyboard, and mouse

Step1: Align the pin 1 of the edge connector between the LCD display and Raspberry pi board, connect the pin 1,2,3,4 then pin 19,20,21,22,23,24,25,26.

Attention: If you want to use the touch function, you need to download and install the driver manually refers to the instructions we provided. The driver includes the settings of the Raspbian OS resolution and touch screen support.

Attention: If you use this display without a Pi, the touch function is not available because the touch function of this display just supports the Raspbian system. Meanwhile, an extra HDMI cable also is required for the video transmission.
