CM4 to CM3 Adapter

This adapter board converts a Raspberry Pi Compute Module 4 (CM4) to the Raspberry Pi Compute Module 3 SODIMM format, allowing you to maintain projects, designs and products that use the older CM3 format by utilising newer generation Compute Modules. The adapter board uses a standard CM4 connector and includes an onboard CM4 ACT status indicator, buck-boost chip to support 3.3V/V power input, power supply selection pads and IO level selection pads. Adapt them all! We have a few other options in the store if you're into this CM4 adapting life:

* CM4 to 3B adapter

* CM4 to 4B adapter

Features

* Onboard standard CM4 connector, support access to CM4 Lite / eMMc series boards

* Onboard standard CM3 SODIMM, easily connected to the original CM3 ecosystem baseboard

* Onboard buck-boost DC chip - supports 3.3V/5V power input

* Onboard ACT LED, can monitor the working status of CM4 in real-time

* Overall dimensions: 67.6mm x 46mm
