Based on the Raspberry PI CMIO board, the OAK-D-CM3 (BW1097) combines a host and the OAK-SoM to allow for fully integrated solution for real-time spatial AI.

Minimal and maximal perceiving distances of the camera¶
Minimal depth perceiving distance of the camera depends on mono camera FOV, resolution, baseline and stereo depth mode, more info is available on the Stereo Depth documentation.
OAK-D-CM3 has a baseline of 9cm and by varying the resolution and stereo depth mode, we get the following minimal depth perceiving distances:
Min distance (800P): ~ 80cm
Min distance (400P): ~ 40cm
Min distance with extended disparity (800P): ~ 40cm
Min distance with extended disparity (400P): ~ 20.9cm
Maximal perceiving distance for OAK-D-CM3: 45.9 meters
For more information about the maximum distance see the Stereo Depth documentation.
The OAK-D-CM3 accepts 5V (+/-10%) from a 5.5m x 2.5mm barrel jack. Raspberry PI USB boot can be accessed by setting a header jumper, which allows initial flash of eMMC on CM3/CM3+. Alternatively the microSD slot can be used with a bootable system image. The Raspberry PI JTAG header is not populated by default, but can be added, allowing JTAG access.
The reset button resets the OAK-SoM only. To reset the CM3/CM3+, ground the RUN header via to the GND header via.
The PWR LED indicates “power good” for the BW1097 on-board PMIC. The ACT LED indicates activity on the CM3/CM3+ device. Other indicator LEDs exist for the two USB2.0 Type A ports and for the 10/100 Ethernet port.
