3: The Type C interface is only used as the USB SLAVE interface to program the image, and cannot be used as a power supply.
4: 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.
5: When CM4 is in normal use, it needs to provide at least 12V 1.5A power supply. Otherwise, there may be problems such as automatic shutdown, frequency reduction and so on.
