The Adafruit DPI TFT Kippah with Touch Support connects a 40-pin TTL TFT display directly to your Raspberry Pi's GPIO header, bypassing the need for an HDMI encoder/decoder. This version adds resistive touchscreen capability via USB, making it suitable for interactive projects and kiosks.
Compatible with Raspberry Pi B+, A+, Pi 2, Pi 3 and Zero, this board works best with 5" and 7" 40-pin TTL TFT displays at 800×480 resolution. The display output is native, delivering full graphics acceleration, instant refresh, and 18-bit colour — the same quality you'd expect from an HDMI connection.
Key Features
- Direct DPI Connection – No HDMI encoder/decoder needed; native GPU-accelerated output
- Resistive Touch Support – USB touchscreen controller built in
- 18-Bit Colour – High-quality display output with full graphics acceleration
- 40-Pin TTL TFT Support – Works with 5" and 7" displays at 800×480
- HAT Form Factor – Snaps directly onto the Raspberry Pi GPIO header
- Fully Assembled – Ready to use with software configuration
Specifications
- GPIO Usage – Pins 2–21 (inclusive) are used by the display
- Available Pins – GPIO #22, #23, #24, #25, #26, #27 remain free
- Compatibility – Raspberry Pi B+, A+, Pi 2, Pi 3, Zero
- OS Support – Tested with Raspbian; other operating systems not guaranteed
Also Available

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
- FPC
- FPC stands for flexible printed circuit, a thin flat flexible cable or connector style often used where space is tight or some movement is needed, commonly for displays, cameras and other high-density connections. Connecting to an FPC connector generally needs a matching cable with the correct pin count, pitch and contact orientation.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
