Truly versatile and practically designed, the Adafruit PiTFT comes complete with a 2.4in. display (320 x 240 16-bit colour pixels) plus a resistive touch overlay. Compatible with Pi Model Zero, A+, B+, Pi 2, Pi 3 – and any Pi with a 2 x 20 connector, this HAT format device slots neatly on top of your Raspberry Pi. It uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) and GPIO #25 and #24. The remaining GPIO are unused.
