Please confirm the fan voltage before connecting. 2: The DSI Display Port is connecting the DSI0 interface of the CM4, and doesn't use the DSI1 display interface. 3: The Type C interface can be used for the power supply or USB SLAVE interface for burning the 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: It needs to use a 5V 2A power supply for CM4. Otherwise, problems such as automatic shutdown, frequency reduction, etc. may occur. 6: When using the M.2 interface, please use the matching screws. Using screws of other lengths may cause the CM4 core to be damaged by the screws. 7: The module doesn't have any protection circuit, please do not short-circuit the power supply. 8: USB2.0 is closed by default, if you need to open it, you need to add dtoverlay=dwc2,dr_mode=host in config.txt. 9.HDMI1 uses a flat cable output, if you need to use it, you can purchase an HDMI adapter. 10.This expansion board does not support the POE function.
