OAK FFC camera modules¶
Overview¶
OAK FFC baseboards and camera modules are great for prototyping flexibility. Since cameras are modular, you can place them at various stereo baselines and select the camera module based on your project requirements (resolution, shutter type, FPS, optics).
OAK FFC baseboards¶
OAK FFC baseboards are OAK devices that have onboard VPU and FFC connectors, to which you can connect OAK FFC camera modules. Here’s the list of our current OAK FFC baseboards:
USB: OAK-FFC-3P, OAK-FFC-4P, OAK-FFC-6P
PoE: OAK-FFC 1P PoE, OAK-FFC 4P PoE
FFC Camera modules¶
Here’s the list of already built OAK FFC camera modules, which you can easily connect to any OAK FFC baseboard with a flat flexible cable. We are working towards offering OAK FFC camera module for all supported CCMs.

FFC camera mounting¶
OAK-FFC Kit is a great way to mount your OAK FFC camera modules. It allows you to easily customize both horizontal and vertical stereo baseline. You can buy it from our shop. For usage, see instruction here.
Mounting adapters can also be found on Github.
Raspberry Pi cameras modules¶
Raspberry Pi sells a number of camera modules that are compatible with the OAK FFC baseboards. RPi cameras can be connected to the FFC baseboard via the RPi Camera Adapter.

Note
The UC-244 Adapter doesn’t work out-of-the-box with the RPi HQ and Global Shutter cameras, additional steps are required and described here.
If you just want to use IMX477, we suggest using Arducam HQ Cam for RPi, IMX477 that works directly with OAK FFC baseboards (without the UC-244 adapter).
M12 mount lenses¶
Some of the FFC camera modules above have M12 mount, so you can use a variety of different lenses (for custom FoV), for example:

and others
M12 selectable FOV¶
Tests were done using 2x OAK-FFC-IMX477-M12 and two different M12 lenses: 20° FOV and 190° FOV one.
