The Adafruit DPI TFT Kippah connects a 40-pin TTL TFT display directly to your Raspberry Pi's GPIO header, bypassing the need for an HDMI encoder/decoder. The result is a fast, native 18-bit colour display with full graphics acceleration and instant refresh — the same quality you'd expect from an HDMI connection.
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. Because the display output replaces HDMI/composite, you get a compact, cost-effective setup without any additional video hardware.
Key Features
- Direct DPI Connection – No HDMI encoder/decoder needed; native GPU-accelerated output

- 1× DPI TFT Kippah circuit board (fully assembled and tested)
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.
