Adafruit this week introduced a new Raspberry PiPiTFT, a 480×320 3.5-inch TFT display, which they have created and will soon be available through its online stores and other retailers. The new Raspberry PiPi TFT comes with a 3.5" display that provides 480 x 320 resolution with 16-bit color pixels and is equipped with resistive touch overlay that is slightly larger than the original PiTFT.
With the original Raspberry Twist TFT, the new PiTFT fits directly on the veneer minicomputer, and is designed to work on raspberry raspberry A or B type, but it also works in completely normal B type +. Even with a small excess USB port of 5mm, Adafruit said. Adafruit explained that the board uses a high-speed SPI interface and can use a small screen as a console, port of the X window, display images or video, etc. Use hardware SPI pins (SCK, Moshi, Meg, CE0, CE1), and GPIO#25 and #24.
GPIO#18 can be used to dim PWM backlight if you like. All other GPIOs are unused. There is a 2x13 leader at the bottom that can be connected to a standard pico GPIO line, using any of the other pins. An awesome customized kernel package based on Notro has been created so that it can be installed on existing Raspbian (or derivative) images in just a few commands.
