Overview

The OAK-FFC 4P PoE baseboard uses PoE for power and connectivity, and has 4 FFC interfaces which allows for:

To see which cameras are compatible with this OAK FFC baseboard, see the guide here: OAK FFC camera modules. Some of camera modules have a M12 mount, so you can use different lenses to get custom FoV (with wide or narrow FOV M12 lenses).

This board uses OAK-SoM-Pro and is also compatible with RPi camera interface. For that you will need a FFC from Arducam, which converts 26-pin Luxonis camera pinout to 22 pin RPi camera pinout.

This device also supports PoE passthrough, so you can daisy chain multiple OAK-FFC 4P PoE boards. As the chip is PoE 802.3af, it can supply up to 15.4W of power, which means you can connect up to 3 devices in a row (as each consumes ~5W of power). Note that if you have longer cables and/or utilize all available computation (NN, Stereo, CV, video encoder, CPU, etc.), it might be that you could only connect 2 devices in a row.

RVC2 inside

This OAK device is built on top of the RVC2. Main features:

Developing with the OAK FFC

After connecting cameras to the baseboard, you can use the utilities/cam_test.py script to quickly test whether cameras are working as expected. By default, it will try to run 2x mono cameras on 2-lane mipi ports B (left) and C (right) and 2x color cameras on port A (rgb) and D (4-lane mipi ports).

If you have different cameras connected, you can specify which camera types to use with the --cameras argument. For example, if you have 3x mono cameras connected to ports A, B, and C, you can run the following command:

python3 cam_test.py --cameras rgb,m right,m left,m

Similarly, to add such configuration into your script you can use the following code:

cam_a = pipeline.create(dai.node.MonoCamera)
cam_a.setBoardSocket(dai.CameraBoardSocket.CAM_A) # Same as CameraBoardSocket.RGB
cam_a.setResolution(dai.MonoCameraProperties.SensorResolution.THE_400_P)

cam_b = pipeline.create(dai.node.MonoCamera)
cam_b.setBoardSocket(dai.CameraBoardSocket.CAM_B) # Same as CameraBoardSocket.LEFT

cam_c = pipeline.create(dai.node.MonoCamera)
cam_c.setBoardSocket(dai.CameraBoardSocket.CAM_C) # Same as CameraBoardSocket.RIGHT

cam_d = pipeline.create(dai.node.MonoCamera)
cam_d.setBoardSocket(dai.CameraBoardSocket.CAM_D)

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 / 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)

  • 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.

FFC cables

For FFC cables we use Molex series 15166. Along with the OAK FFC board, we ship 26 pin count, same-sided, 152mm cables (part number 151660281). If you would like to use shorter/longer FFC cables, you can get them here.

Known errata

  • It is not possible to power the OAK-FFC-4P-POE via the USB-C connector. So to connect through the USB-C, you will need to power via RJ45 (POE).
