The PiTFT got even better with this little primary display for Raspberry Pi in HAT form! It features a 2.2″ display with 320×240 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 2×13 header (not included) instead of the included 2×20 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 2×20 GPIO header. Some light soldering is required to attach the 2×20 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!

Technical Details
Revision History:
- As of December 20, 2022 – we’ve updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen – you may get the new PCB or the older version with vector fonts – both are identical other than the fancy silkscreen.
- As of July 28, 2016 we have a version that breaks out the GND, 3.3V and 5V power pins as well
Specifications:
- Board Dimensions: 65mm x 57mm x 6mm / 2.6″ x 2.2″ x 0.2″
- Screen Dimensions: 55mm x 40mm / 2.2″ x 1.6″
- Datasheets, schematic, PCB files, and Fritzing available in the product tutorial
