Double your GPIO access on the Raspberry Pi 400 with this dual-header adapter. Converts the Pi 400's rear GPIO connector into two standard 40-pin headers, allowing you to connect multiple HATs or accessories simultaneously. Features colour-coded pin headers for easy identification of power, ground, and GPIO pins during prototyping and development. Key Features Dual 40-Pin Output – Two headers from one Pi 400 GPIO port Pi 400 Compatible – Designed specifically for Raspberry Pi 400 Colour-Coded Headers – Easy visual identification of pin functions Use Multiple Devices – Connect two HATs or accessories at once Compatibility Raspberry Pi 400 Standard 40-pin HATs and pHATs GPIO breakout boards Breadboard jumper wires Ideal For Using multiple HATs with Pi 400 Complex prototyping setups Electronics education requiring multiple GPIO connections Note: When using multiple devices, ensure they don't conflict by using the same GPIO pins or I2C addresses.
