Jun-Electron for Raspberry Pi 3 B+ 3.5 inch Touch Screen with Case, 320x480 Pixel Monitor TFT LCD Game Display [Support Raspbian, Ubuntu, Kali, RetroPie System]

The product comes with everything you need to get it set up and running out of the box. It comes with the LCD screen, a black case to secure it, a top that can replace the LCD screen to support a fan, a heatsink to put on your pi itself, a stylus and an instruction guide. The screen and case fit snugly together. The LCD screen works well and seems to have surprisingly high resolution for such a small screen.While the touchscreen function works, it doesn’t work well enough to replace a physical keyboard. The stylus should be used with the touchscreen, as it needs a firm poke to register.I tried using both raspbian and Kali on this. Raspbian installation instructions are provided with the setup, and they work well. If you want to install Kali though, you’ll need ti use a different driver. I belive I used one on GitHub for mine to work. My last review got removed assumably by containing a link, so you’ll have to google “Kali Linux 3.5 lcd” and click the first link (should be GitHub) to get the right driver.

Wow, it comes with a case and heatsinks. It was really easy to put together and the included instructions were really easy to follow to get the display working. The touchscreen works and the display is bright and good enough to use in a terminal. Note: to rotate screen, run the rotate.sh script with desired screen rotation, the rest is taken care of for you.The screen doesn't have very good view angle support, it only works well if youre looking on it straight on, but I highly doubt anyone who is making a device with a screen like this really cares about stuff like LCD view angle.

I found this touch screen to be generally very easy to install and the price was appropriate. The physical assembly was straightforward with one exception that the instructions for the corner standoff strain relief did not exactly match the hardware I received. The software was pretty easy to set up too. I tried installing their pre-packaged images as well as pulling the driver installation from git onto Raspbian. They all worked flawlessly. I do wish it was easier to find the electrical pinout and the make/model of the LCD screen so that I would know what pins are available for other purposes.

Pros:+ great display, outstanding value for the $$+ installed right onto my Pi 3Cons+ they ship different versions! e.g. mine came without a fan, though the screen has a 2-pin receptacle for a fan. You can order "JST-PH 2.0" male connector if you need one to allow installing your own fan+ polarity (red/black) on the fan receptacle is reversed+ the supplied instructions didn't match the display sent -- e.g. I needed a different driver version (LCD35-show instead of MHS35-show). Your download will pull about 20 different versions of drivers, just find the right one.+ also the spacer post installation was different from how described, and required removing a plastic sticker.+ with the supplied case increases CPU temp about 10C, to 50C. Not the end of the world frankly.+ despite the dedicated "Fan" receptacle, no apparent way to control fan speed+ no way to control screen brightnessCPU Temperature control:My temperature (under light load .. just running pihole and PADD) increased from ~40C to 50C. There just is no ventilation with this screen installed. Suggestions:1. drill lots of vent holes around the side of the case2. install a fan. if you can squeeze one inside the case (probably a 30x30x10mm) then let us know how that went. However I installed a Noctua 40x40x10 5V on the outside -- bottom side of the case, even though the CPU is on the topside of the motherboard. See photo (including the polarity reversal on the connectors).This brought my CPU temp down to 38C, even cooler than it was before I switched cases to use this display.
