## Description

The GPIO Edge Extension Board offers enhanced accessibility and flexibility for Raspberry Pi projects by providing both vertical and horizontal GPIO pin access. This dual-access design revolutionises how sensors, displays, and other hardware components can be connected to any 40-pin Raspberry Pi, making it an invaluable tool for development and prototyping.

 Key Features - Dual-access design with both vertical and horizontal GPIO headers
- Compatible with all 40-pin Raspberry Pi models including Pi 5, 4, 3B+, 3A+, 3, 2, B+ and Zero family
- Direct pin duplication without software control - perfect for power distribution
- Simplified access to GPIO pins in space-constrained environments
- Ideal for custom enclosure designs and hardware prototyping
 
 How to Use Installation is straightforward - simply align the extension board with your Raspberry Pi's GPIO pins and press firmly to ensure a secure connection. The horizontal pins provide alternative access points for components, while the vertical pins maintain compatibility with standard HATs and add-on boards.

For expanded connectivity, combine with a [Raspberry Pi GPIO 40-Pin Ribbon Cable](https://core-electronics.com.au/raspberry-pi-400-ribbon-cable.html) to extend your GPIO connections further. When using the duplicated pins, remember that each pair shares the same connection - they cannot be used for different functions simultaneously.
