Binocular Camera Base Board for CM4 with Interface Expander

This binocular base board for the Raspberry Pi Compute Module 4 is perfect for evaluating the CM4 for stereo vision, depth vision, AI applications, robotics and more, with the onboard dual IMX219 8MP cameras with up to 3280×2464 resolution per camera.

The main base board includes a slot for your CM4 board and also offers a number of handy features such as a MicroSD slot, full-size HDMI slot (4K 30FPS), Gigabit Ethernet, USB-C (power/programming), USB 2.0 port and additional interface FFC connectors for the included Interface Expander board.

The included Interface Expander adds to this by giving the user another USB 2.0 port, another HDMI port, a 40-pin GPIO connector, M.2 M-Key slot for NVMe SSDs and more.

With the base and expander assembled together, there’s still room for this CM4 heatsink to keep temperatures in check.

CM4 not included.
