I had to check out the latest Raspberry PI 2.0 with a 3.5″ 320×480 TFT screen.
It’s an easy install, and simple to get up and running with a resistive image from Adafruit.
I installed Linux Jessie but you can also load it up with Windows 10
There are some calibration that one can get into in regards of touch zones etc.
I haven’t quite figured out what I will use it for yet, but I am sure there will be some project.. 🙂
