It features a 2.8" display with 320x240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! This updated design fits perfectly onto the Pi Model A , B , or Pi 2! Works just like the Model B version, but now matches the outline of the Raspberry Pi 2 and Model B . It also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath. Now that it's the same outline as a Pi 2/B it fits well on top of a Pi in our Raspberry Pi Enclosure base. The display and touchscreen uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused. Plus there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
