Notes

• The USB SLAVE interface is used to burn the image and cannot be used as an OTG interface.
• In normal use, it is necessary to provide at least 5V 2.5A power supply for CM4. Otherwise, there may be problems such as automatic shutdown and frequency reduction
• Onboard default 4-way USB 2.0 interface.
• Supports PoE via 4-pin header, additional PoE HAT is required for PoE
• The display requires a driver
• Do not plug and unplug any device except USB and HDMI while the baseboard is working
• If the fan needs to be replaced, please confirm the fan voltage and then power on
