OAK-FFC-3P-OG¶
Overview¶
Warning
We recommend using the OAK-FFC-3P, the latest model, unless you are sure you need this one.
The OAK-FFC-3P-OG (BW1098FFC) baseboard has three FFC interfaces which allows 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.
Baseboards and cameras (BW1098FFC + OAK-FFC-OV9282 + OAK-FFC-IMX378) together:
RVC2 inside¶
This OAK device is built on top of the RVC2. Main features:
4 TOPS of processing power (1.4 TOPS for AI - RVC2 NN Performance)
Run any AI model, even custom-architectured/built ones - models need to be converted.
Encoding: H.264, H.265, MJPEG - 4K/30FPS, 1080P/60FPS
Computer vision: warp/dewarp, resize, crop via ImageManip node, edge detection, feature tracking. You can also run custom CV functions
Stereo depth perception with filtering, post-processing, RGB-depth alignment, and high configurability
Object tracking: 2D and 3D tracking with ObjectTracker node

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 this device has modular mono cameras, you can choose a custom stereo baseline (depending on how it is set up). When using OAK-FFC-OV9282, the formulas for min/max depth perceiving distances are:
Min distance (800P) =
882.5 * baseline / 95Min distance (400P) =
441.25 * baseline / 95Min distance with extended disparity (800P) =
882.5 * baseline / 190Min distance with extended disparity (400P) =
max(441.25 * baseline / 190, 19.6)Max perceivable distance (using subpixel) =
baseline/2 * tan((90 - 71.9/1280) * PI/180)
For more information about the maximum distance see the Stereo Depth documentation.
Getting started¶
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.
