The OAK-FFC-3P-OG (BW1098FFC) baseboard has three FFC interfaces which allow for two OAK-FFC-OV9282 camera modules (stereo pair) and one OAK-FFC-IMX378 RGB camera module. This board can also be used with adapters for the Raspberry Pi HQ Camera, using the Raspberry Pi Adapter Board.

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.
Since OAK-FFC-3P-OG has modular mono cameras, it also has a custom baseline (depending on how it is set up). The formulas for minimal depth perceiving distances are:
Min distance (800P) =
882.5 * baseline / 95
Min distance (400P) =
441.25 * baseline / 95
Min distance with extended disparity (800P) =
882.5 * baseline / 190
Min distance with extended disparity (400P) =
max(441.25 * baseline / 190, 19.6)
Maximal perceiving distance for OAK-FFC-3P-OG =
baseline/2 * tan((90 - 71.9/1280) * PI/180)
For more information about the maximum distance see the Stereo Depth documentation.
The OAK-FFC-3P-OG accepts 5V (+/-10%) from a 5.5m x 2.5mm barrel jack, and interfaces to a host via USB 3.1 Gen1 Type-C. With cameras and the OAK-SoM, total power consumption usually stays below the 900ma specification of USB 3, but Type-C power of 1.5A or greater is recommended.
Interfacing with the OAK-SoM is also possible with OAK-FFC-3P-OG connector pads J3, J4, and J5. These pads are designed for the Amphenol/FCI 20021121-00010T1LF or equivalent. Please refer to the schematics for pinout information.
The reset button resets the OAK-SoM only.
The 5V LED indicates 5V power is present on the OAK-FFC-3P-OG. The PG LED indicates “power good” from the OAK-SoM. The “RUN” LED indicates that the OAK-SoM is not in reset.
