Overview

I am a CM4 duino basic expansion board, an expansion board that can be used with Raspberry Pi Compute Module 4, and supports 5V DC power supply with Typc-C interface. Onboard HDMI interface, one CSI interface and one USB interface, standard arduino interface, etc...

Precautions for use

1: Do not plug and unplug any device except USB and HDMI when powered on
2: Type C interface can be used as power supply or as USB interface to burn image (need to use BOOT switch to switch)
3: In order to ensure the normal power supply of CM4, please do not connect other devices when using the Type C interface to burn the image.
4: When CM4 is in normal use, it needs to provide 5V 2A power supply for CM4. Otherwise, there may be problems such as automatic shutdown, frequency reduction and so on.
5: USB2.0 is closed by default, if you want to open it, you need to add dtoverlay=dwc2,dr_mode=host in config.txt
