Raspberry Pi 40 Pin GPIO Double Expansion Board
Double your GPIO access with this 40-pin expansion board for Raspberry Pi. Connects to your Pi's GPIO header and provides two parallel 40-pin outputs, allowing you to connect multiple HATs, breakouts, or accessories simultaneously.
Perfect for complex projects where you need to use multiple GPIO-connected devices without stacking them directly on the Pi.
Key Features
- 1-to-2 Expansion – Single input, dual 40-pin outputs
- Full GPIO Access – All 40 pins duplicated to both outputs
- Side-by-Side Layout – Connect devices without stacking
- Easy Installation – Plugs directly onto Pi GPIO header
Compatibility
- All 40-pin Raspberry Pi models (Pi 2, 3, 4, 5, Zero)
- Standard HATs and pHATs
- GPIO breakout boards
Ideal For
- Using multiple HATs simultaneously
- Prototyping with multiple GPIO devices
- Projects requiring duplicate GPIO access
