This GPIO header adapter is designed specifically for the Raspberry Pi 400, converting its rear-mounted 40-pin GPIO header into two standard 40-pin headers for easy expansion. The colour-coded header makes it simple to identify pins at a glance.
Since the Raspberry Pi 400's GPIO header faces outward from the rear of the keyboard, this adapter provides a convenient way to connect HATs, breadboards, and other accessories that expect a top-facing header.
Key Features
- Dual 40-Pin Headers – Two standard 2×20 GPIO headers for flexible expansion
- Colour-Coded Pins – Easy identification of power, ground, and signal pins
- Designed for Pi 400 – Purpose-built for the Raspberry Pi 400's rear GPIO layout
Ideal For
- Connecting HATs and pHATs to the Raspberry Pi 400
- Breadboard prototyping with the Pi 400
- Running multiple GPIO expansion boards simultaneously
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
