Introduction CM4-IO-BASE-A is an IO board designed for Raspberry Pi Compute Module 4, it can be used with all versions of CM4, suitable for evaluating the Raspberry Pi CM4 or beingintegrated into end products. Precautions for Use 1: It is forbidden to unplug and plug any equipment other than USB and HDMI when power is on 2: FAN fans only support 5V fans. 12V is not supported. Confirm the fan voltage before connecting. This version of the fan does not have a controller and cannot be adjusted in speed. 3: The DSI display interface is the DSI0 interface, and the DSI1 display interface is not connected. 4: Type C interface can be used for power supply or USB SLAVE interface for burning image. 5: 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. 6: 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. 7: 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. 8: The module does not have any protection, please do not short-circuit the power supply. 9: USB2.0 is closed by default, if you need to open it, you need to add dtoverlay=dwc2,dr_mode=host 10: If you want to use HDMI1 alone, you can purchase it separately if you need to use it HDMI Adapter 11: Both USB 3/4 and HDMI1 need to be used, you can use adapter board to connect it out 12: This expansion board does not support the POE function. 13: M.2 interface power supply is limited to 1.5A, if it causes problems such as slowing down of solid state or other equipment, it is recommended to buy version B Package Content 1.
