LORDWORLD CM5 to Pi5 Adapter Board 40PIN GPIO development board

CM5-to-Pi5 adapter for embedded developers

This adapter board lets developers replicate the Raspberry Pi 5 I/O layout using a Compute Module 5. It targets engineers building custom carrier boards, edge devices, or production test platforms. The design supports both CM5 Lite and eMMC variants, so the same board works across development and volume deployment.

Practical limits of the 40PIN GPIO interface

The board exposes a 40PIN GPIO header that mirrors the Pi 5 pinout, enabling software porting and hardware reuse. Only the interfaces physically routed to this header and the onboard HDMI and USB ports are available; any additional Pi 5 peripherals not mapped here cannot be used. Audio input and output rely on the integrated USB audio decoder chip and microphone header.

Compute Module 5 socket compatibility decides fit

The single specification that determines whether this is the right part is the standard CM5 socket, which accepts both Lite and eMMC Compute Module 5 boards. Projects requiring a different module form factor or a non-Pi-5 pinout cannot use this adapter.
