CM Stereo Vision Expansion Board For Raspberry Pi Compute Module, Small Size
This binocular stereo vision expansion board is specially designed for Raspberry Pi Compute Module, compatible with CM3 / CM3 Lite / CM3+ / CM3+ Lite. It features three camera ports and common used ports like DSI and USB, more other peripheral interfaces are also supported through the FPC connector, all in the small size body.
By connecting with various sorts of cameras, combined with the included IMU fill light board, it is easy and flexible to build different Raspberry Pi stereo vision projects such as binocular parallax ranging, facial identification, living object detection, VR video recording, and so on.
User Manual / Datasheet / Example Codes Etc.
Features
- Compatible with Raspberry Pi Compute Module CM3 / CM3 Lite / CM3+ / CM3+ Lite.
- Three camera ports, CAM0 port for default use, and CAM1/CAM3 ports are two alternative options selected by GPIO.
- Onboard DSI port allows direct connecting with DSI display.
- Onboard USB connector, convenient for flashing system image, or used as a regular USB port.
