Note

1. Do not unplug any device except USB and HDMI when the power is on.
2. Check the fan voltage before connecting. It supports 5V and 12V. The default connection is 12V. Before switching, please modify the resistance of FAN_VCC.
3. The Type C interface is only used as a USB SLAVE interface to burn images, and cannot be used as a power supply.
4. When CM4 is in normal use, it needs to provide at least a 12V 1.5A power supply. Otherwise, problems such as automatic shutdown and frequency reduction may occur.
5. See instructions for use about Opwenwrt.
6. This expansion board does not support the POE function.
