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. USB 2.0 is closed by default, and you need to add "dtoverlay=dwc2, dr_mode=host" in "config. txt" when using.
