    Precautions for use

    1: It is forbidden to unplug and plug any equipment other than USB and HDMI when power is on
    2: Confirm the fan voltage before connecting. It supports 5V and 12V. The default connection is 5V. Please modify the jumper of FAN_VCC
    3: Type C interface can be used for power supply or USB SLAVE interface for burning image.
    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 5V 2A power supply for CM4. Otherwise, problems such as automatic shutdown, frequency reduction, etc. may occur.
    6: USB2.0 is closed by default, if you need to open it, you need to add dtoverlay=dwc2,dr_mode=host
