Specifications CM4 socket:suitable for all variants of Compute Module 4 Networking:Gigabit Ethernet RJ45 connector Connector :M.2 M KEY, supports communication modules or NVME Solid State Drives, Raspberry Pi 40PIN GPIO header. USB: USB 2.0 Type A x 2 Display: LCD port (40pin 0.5mm FPC connector) Camera: MIPI CSI-2 camera port × 2 (15pin 1.0mm FPC connector) Video: HDMI port, supports 4K 30fps output RTC: Real-time clock with battery socket and ability to wake Compute Module 4 Storage: TF card socket for Compute Module 4 Lite (without eMMC) variants Fan header: allows speed adjustment, 5V Power input: 5V Dimensions: 85 x 56mm precaution for using 1. Do not unplug any devices except USB and HDMI when powering on. 2. Only support fans with 5V, and 12V is not supported. Please check the voltage of the fan before connecting. 3. Only support LCD direct connection as there is not a DSI interface. 4. Type C interface can be used as the power supply or the USB SLAVE for programming images. 5. In order to ensure the power supply of the CM4, please do not connect to other devices when programming the images with the TypeC interface. 6. When using CM4, you must provide 5V 2A for it, otherwise, it may shut down, lower frequency or etc. 7. Please use the matching screws when using the M.2 interface as CM4 may be damaged if you use other screws. 8. The module does not have any protection, please do not short-circuit the power supply. 9. USB2.0 is closed by default, and you need to add "dtoverlay=dwc2,dr_mode=host" in "config.txt" when using. 10. This expansion board does not support POE function.
