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.
We have a few other options in the store if you're into this CM4 adapting life:
