Excellent little display. I wrote a library to interface a teensy 3.5/6 to the adafruit GFX using the 8 bit port and its lightening fast at displaying graphics. Heres my home made sampling scope/ logic analyser showing sine and sawtooth waveforms. Looking to interface a camera to see how fast I can get full motion graphics on it.
Careful of the touch screen flexible cable as its prone to being broken.
