I bought this in November 2020 to use with TouchUI and Octoprint on a Raspberry Pi 3B+. I didn't have a graphical desktop installed and did everything from the Raspian terminal. Installation was pretty easy. Immediately after connecting it works like a normal monitor without drivers installed. For me it was in 1080p, so I couldn't see much on the tiny 3.5-inch screen. So I connected the Pi to my regular monitor and followed the instructions in the package to install the drivers. Anyone can do this in a terminal as long as you can read and accept the fact that you have no idea what you are doing :) Once this is complete my normal monitor stops working so I reconnected the utronics and there it is! Beautiful 480p. Excellent clarity and color. I later had to go through a few other steps to get it working with Octoprint, but that's another story. Bottom Line: You may be surprised at how small 3.5 inches is, but if you know what you want then the product is great. . Bonus for the cheapest screen. I recommend it.
