Raspberry Pi CM4 to CM3 Adapter User Guide

Overview

Since the Raspberry Pi Compute Module 3 (CM3) module is in short supply, the CM4 to CM3 adapter is designed to convert CM4 module to CM3 interface.

This adapter board converts the latest Raspberry Pi Compute Module 4 (CM4) to CM3 interface, allowing CM4 to adapt to the old CM3+/CM3/CM3L series baseboard. Also Support to use CM4 with Geekworm 12mm aluminum alloy heatsink C235.

When install the CM4 module into CM4 to CM3 adapter board, please pay attention to the CM4 install directions.

Note：

Make sure that the CM4 module is installed on the expansion board correctly before power on.
Please pay attention to the CM4 install directions.
The Raspberry Pi Compute Module 4 or heatsink is not included in the packing list.
