ALLNET Rock Pi GPIO Extension Board (RockGPIOExtention)

The ALLNET Rock Pi GPIO Extension Board (RockGPIOExtention) is a high-quality PCB accessory designed to expand the GPIO capabilities of Rock Pi single-board computers. It provides a 1:1 passthrough pinout, allowing easy access to all 40 GPIO pins for prototyping, breadboard connections, and peripheral expansion.

Advantages

This extension board simplifies development by offering two male 40-pin headers, enabling simultaneous connections to multiple peripherals. The clearly labeled pins (VCC, GND, GPIO numbers) reduce wiring errors, and the compact design directly plugs onto the Rock Pi GPIO header without additional cables.

Suitable for

• Rock Pi 4 Series (A, B, C, Plus)
• Rock Pi 5
• Other Rock Pi models with standard 40-pin GPIO header

Key specifications
