Raspberry Pi 400 GPIO Header Adapter, Header Expansion, 2x 40PIN Header
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
