CM4-DUAL-ETH-BASE is a base board that can be used with Raspberry Pi Compute Module 4, and supports 7~12V DC power supply, onboard three USB3.2, dual Gigabit Ethernet ports and it is suitable for scenarios that require multiple network ports, such as soft routing.

Precautions for use

• 1: Do not plug and unplug any device except USB and HDMI when powered on.
• 2: Confirm the fan voltage before connecting, support 5V and 12V, connect 12V by default, please modify the resistance of FAN_VCC when switching.
• 3: The Type C interface is only used as the USB SLAVE interface to program the image, and cannot be used as a power supply.
• 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: When CM4 is in normal use, it needs to provide at least 12V 1.5A power supply. Otherwise, there may be problems such as automatic shutdown, frequency reduction and so on.
• 6: For Opwenwrt, see the instructions for use.
• 7: This expansion board does not support POE function.
