Guides for product: Adafruit PiTFT - 320x240 2.8" TFT+Touchscreen for Raspberry Pi
Is this not the cutest little display for the Raspberry Pi? 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!
It's designed to fit nicely onto the Pi 1 Model A or B but also works OK with the Pi 4, Pi Zero, Pi 3, Pi 2 or Pi 1 Model A+ or B+ (any Pi with a 2x20 connector) as long as you don't mind the PCB overhangs the USB ports by 5mm, see the photos above. If you have a modern Pi with a 2x20 connector, you may want to grab a PiTFT 2.8" Plus which does not overhang
Uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused. Since we had a tiny bit of space, there are 4 spots for optional 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. See below for the link to get the optional tact switches, they're not included.
As of 8/15/2014 it comes fully assembled and ready to plug into your Pi! The photos above also show the optional installed slim tactile buttons. The tactile buttons are not included, but you can pick up a pack of 20 here. Some basic soldering is required to install the buttons.
We've 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. Our tutorial shows you how to install the software, as well as calibrate the touchscreen, show videos, display images such as from your PiCam and more!
