Raspberry Pi Compute Module 4 CM4-DUAL-CAMERA-BASE User Guide
Overview
This is a binocular camera based board that is designed for Raspberry Pi Compute Module 4. Two IMX219 800MP cameras are integrated for the stereo vision projects. An interface expander board is optional for connecting other accessories.
Note
1: It is forbidden to unplug and plug any equipment other than USB and HDMI when power is on
2: Type C interface can be used for the power supply or USB SLAVE interface for burning images.
3: 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.
4: When CM4 is in normal use, it needs to provide 5V 2A power supply for CM4. Otherwise, problems such as automatic shutdown, frequency reduction, etc. may occur.
5: The module does not have any protection, please do not short-circuit the power supply.
6: The USB2.0 interface is disabled by default, you should add line dtoverlay=dwc2,dr_mode=host to the /boot/config.txt file to enable it.
7: This board doesn't support PoE function.
