The PiTFT got even better with this little primary display for Raspberry Pi in HAT form! It features a 2.2" display with 320x240 16-bit color pixels. The HAT 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 of your Model A+ or B+ and fits into the Cyntech and Adafruit Model B+ cases quite nicely.
It's designed to plug directly onto the Pi Model A+ or B+. While not specifically designed for Pi Model A or B, you can use it with A/B if you solder in an extra-tall 2x13 header (not included) instead of the included 2x20 header
This design uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25. All other GPIO are unused and are available on a 25-pin long breakout line. There are 4 flat 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.
Comes as a fully assembled display PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder.
To make it super easy for use: Adafruit has created a custom kernel package based of off Notro's awesome framebuffer work, so you can install it over your existing Raspbian (or derivative) images in just a few commands. Their tutorial series shows you how to install the software, play small videos, or display images such as from your PiCam and more!
