Extends the 40 pin GPIO at both ends to support multi angle adaptation and flexible mounting angles. Includes vertical and horizontal vertical/horizontal dual pin headers, providing 2x20 pins for versatile layout options. GPIO Edge Extension exposes the full 40 pin GPIO header for convenient external access and wiring. Lead outs are aligned with the GPIO layout to maintain consistent compatibility across devices. Benefits: improves accessibility for testing and wiring, enables flexible installation in tight spaces, and preserves standard GPIO compatibility for reliable connections. Specifications and compatibility: suitable for devices with a 40 pin GPIO header; supports both vertical and horizontal mounting using 2x20 male headers. Use scenarios: Prototyping and testing: easily connect sensors, LEDs, and modules from the edge without obstructing the main board. Tight or edge mounted installations: choose the orientation that fits your enclosure or chassis while keeping pins accessible. Debugging and development: quick access to all 4 GPIO pins for measurements, signal inspection, or skipping intermediate adapters.
