This adapter board converts a Raspberry Pi Compute Module 4 (CM4) to the Raspberry Pi 3B format, allowing you to maintain projects, designs and products that use the older Raspberry Pi 3B format by utilising the newer generation Compute Modules.
The adapter uses a standard CM4 connector on the rear of the board, breaking out to the full 3B footprint with all connectors.
Please do not connect to other devices when programming the image by micro USB so as to ensure the CM4 can be powered on normally
When using CM4, you need to provide 5V/4A
USB 2.0 is closed by default, if used dtoverlay=dwc2,dr_mode=host should be added in config.txt
Only supports a 5V fan (12V is not supported.) The speed of the 5V fan cannot be adjusted without a controller
DSI interface is DSI1
Micro-USB port is for power supply and for programming images USB SLAVE
Adapt them all!
We have a few other options in the store if you're into thisCM4 adapting life:
