3.5" HDMI LCD Touch Screen for Raspberry Pi 5 4 3 2 with Stylus Pen

The screen is great, I haven't set up the touch capability because it may interfere with other components. I need to check the protocol/pins for the various components, I may try to get the ribbon for the touch free so that I can use it as a USB 'mouse'. The only issue i have is that the included HDMI connector did not work. Under the same settings works perfectly with an HDMI cable, I think there may be a short because there is what appears to be a solder connection between two of the pins. This is a shame because the connector would have made the conclusion of project easier and more elegant. Over all A+ for the screen but F for the HDMI connector. Update-> I contacted the seller about the connector and within a day they responded and said they'll send a replacement tomorrow. Great costumer service. If the replacement works I'll change to 5 star Update 2=> they provided a tracking number for the replacement connector. Update 3=> the replacement HDMI connector arrived today, works perfectly. Changing rating to 5 star. As a note getting the replacement was quite painless, the seller was responsive and shipped the connector within a couple days at no charge.

Seems to be a good display though it is not exactly plug-n-play. You have to configure the os to get it to work which was a bit of a pain. I did not set up the touch screen as I am using it with a lite version of Raspberry Pi OS. The web site only has instruction for using xwindows graphical method. I almost sent this back, but I finally was able to get it to work.

Can’t say how the touch screen or the GPIO adapters work, but using it via hdmi as an extra screen for a pc works great. Sharp picture and the viewing angle is actually fairly good. There are no mount tabs which makes it hard to use for non-conventional projects though. But I can’t knock it for that because I knew that before purchasing. All and all I would buy another in a second. My computer wouldn’t recognize it’s native resolution and set it at 720p but setting a custom resolution in the graphics card settings resolved that issue.

The screen works nicely on Rasberry Pi 5, but the touch doesn’t work. Followed the instructions and also tried an online video instruction. I like the separate HDMI port and power. Lots of options. Maybe after some time, the RP5 instructions will get updated for the touch function.

It gets REALLY hot, like... I don't feel comfortable putting this into a 3D printed enclosure because it will probably deform it. -- there are no mounting points either; so you have to design the enclosure for the PI to mount, and that leads to a lot of design churn... -- also it comes on and has a lot of OSD stuff going on (static and then a splash screen image and then "HDMI" at the end), and the text it displays ends up being too tiny to read. -- It sucks so much power from the PI that you will constantly get undervolt warnings (probably all that heat it's producing...) -- OH!! And not to forget, the four corners are DARK, like the backlight is not even... it leaks a ton of light out the edges, but then the four corners fade to black, and you can't see the image there... the backlight switch is either on or off (off is useless because you can't see anything), there is no wheel to dial it or anything... :(

I bought this for a Raspberry Pi Zero hand held I have been working on. I see a lot of questions about using this screen for similar things. I started with a Adafruit 35r using the GPIO and the refresh rates using the frame buffer were just impossible and unsatisfactory. I didn't have to do anything special to my installation when I recieved this board; I simply plugged it in and it worked perfect right away. If you have problems with it turning on with your software running your RPI you need to look at your HDMI settings in your /boot/config.txt and verify you have the hdmi output enabled. For my build I don't care about the touch screen portion so I am not using the GPIO pins associated with the touch screen portion. For that part to work you will need to find a driver that is compatible; there are plenty of resources via google. In the package is the hdmi splitter which worked great; I put my mini hdmi cable into it right into my zero. It also comes with a stylus. What I recieved (seems to be some confusion in the questions section) is exactly what is pictured here, and I am very happy with the results! There is a version of this screen for like 10 dollars cheaper without hdmi. But for my build; to achieve even close to 30fps without lag, this is the way I needed to go. The zero with a single core processor just doesn't have the processing power to run the frame buffer and emulation remotely in sync. This is a perfect solution.

Got this screen because i needed a very small screen for a very dumb project. And having tried another screen before this one. I frankly can't complain with what i got here. The image quality and refresh rate are good for anything you'd use this for, and even watching some tv shows on this i've had no trouble. Now the touch screen feature is mushy, thus you gotta press a bit. Which isn't that great since you just got the gpio and hdmi holding it. And isn't super smooth or accurate touch screen, but it's a cheap 3.5 inch screen, and works fine for just moving about on the screen. Now it's an easy install, just pop it on and it works. installing the drivers is ok. Frankly only complaint with the install really is the screen using up power for a fan, because this thing now gets pretty warm.

Really nice little screen; you will not be disappointed. It handles audio for you and everything. The image is bright, clear and smooth.

Got it a while ago, haven't used it until now. Works great, My only issue is everything seems to be squished horizontally regardless of the source I plug it in to. This wouldn't be a problem if I wasn't switching my Pi on different screens. Anyone know why this happens?

Looks ok for old games and 480p video, but I wouldn't recommend watching 1080p movies on.
