Do not plug or unplug any device other than a USB while it is powered on. 2. Confirm the fan voltage before connecting, only 5V fans are supported. 3. The Type C interface can be used as a power supply or as a USB interface to program the image (need to use the DIP switch to switch). 4. In order to ensure the normal power supply for CM4, please do not connect other devices when using the Type C interface to program the image. 5. 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. 6. USB 2.0 is closed by default, if you want to open it, you need to add "dtoverlay=dwc2, dr_mode=host in config. txt". 7. For Opwenwrt, see the instructions for use. 8. This expansion board does not support the POE function. Package Content CM4-DUAL-ETH-MINI x1 Note 1. Online development resources are provided, please contact with if you you need. 2.
