Overview

The OAK-FFC-3P (DM1090FFC) baseboard has 3 FFC interfaces which allows for:

Note

If you would need 4 FFC interfaces, see OAK-FFC-4P.

Please note that only revision R1M1E1 and newer camera modules can be connected to this OAK FFC board.

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 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.

In addition, IMU (over SPI) sensor is also added to this OAK FFC board.

RVC2 inside

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

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 percievable 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 is powered via USB Type-C or from a 5V, 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 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 boot button overrides boot mode to USB boot if different boot mode is set in NOR Flash and BW1099EMB SoM is used.

The 5V LED indicates 5V power is present on the OAK-FFC-3P. The PG LED indicates “power good” from the OAK-SoM. The “RUN” LED indicates that the OAK-SoM is not in reset.

FFC cables

For FFC cables we use Molex series 15166. Along with the OAK-FFC-3P, 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.

Revision info

USB designs with FFC camera boards contain 3 different iterations, below is a flowchart which tries to explain the design progress flow:

Note

The first two revisions (BW1092FFC and DM1098FFC) were also named F1, and the newest revision (DM1090FFC) is named F2.
