Overview
********

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

- **Two 2-lane MIPI** camera modules, eg. :ref:`OAK-FFC-OV9282 <bg0250tg>` (stereo pair)
- **One 4-lane MIPI** camera modules, eg. :ref:`OAK-FFC-IMX378 <bg0249>` RGB camera module, or additional :ref:`OAK-FFC-OV9282 <bg0250tg>` if RGB camera module is not required

.. note::
  If you would need 4 FFC interfaces, see :ref:`OAK-FFC-4P`.

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

This board is also compatible with RPi camera interface. For that you will need a `FFC from Arducam <https://www.arducam.com/product/arducam-12mp-imx477-mini-high-quality-camera-with-m12-mount-lens-and-adapter-board-for-depthai/>`__,
which converts 26-pin Luxonis camera pinout to 22 pin RPi camera pinout.

To see which cameras are compatible with this OAK FFC board, see the guide here: :ref:`compatible Arducam cameras <arducam-compatible-cameras>`.
Those cameras have a M12 mount, so you can use different lenses to get **custom FoV** (they have wide and narrow angle M12 lenses).

In addition, IMU (over SPI) sensor is also added to this OAK FFC 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 <https://docs.luxonis.com/projects/api/en/latest/components/nodes/stereo_depth/#min-stereo-depth-distance>`__.

Since OAK-FFC-3P 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) = :code:`882.5 * baseline / 95`
- Min distance (400P) = :code:`441.25 * baseline / 95`
- Min distance with extended disparity (800P) = :code:`882.5 * baseline / 190`
- Min distance with extended disparity (400P) = :code:`max(441.25 * baseline / 190, 19.6)`

Maximal perceiving distance for OAK-FFC-3P = :code:`baseline/2 * tan((90 - 71.9/1280) * PI/180)`

For more information about the maximum distance see the `Stereo Depth documentation <https://docs.luxonis.com/projects/api/en/latest/components/nodes/stereo_depth/#max-stereo-depth-distance>`__.

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 
:ref:`OAK-SoM <bw1099>`, 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 <https://github.com/luxonis/depthai-hardware/tree/master/SoMs/BW1099EMB/R1M0E1>`__ 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 <https://www.molex.com/molex/search/partSearch?query=15166>`__. Along with the OAK-FFC-3P, we ship
**26 pin count, same-sided, 152mm** cables (part number `151660281 <https://www.molex.com/molex/products/part-detail/cable/0151660281>`__).
If you would like to use **shorter/longer FFC cables**, you can get them `here <https://www.molex.com/molex/search/deepSearch?pQuery=q%253D*%253A*%2540fq%253Dcollection%253Aimpulse%2540fq%253Dcollection%253Aimpulse%2540fq%253Dproductseries%253A%252215166%2522%252BOR%252Bengineeringnumber%253A%252215166%2522%2540fq%253Dcategory%253A%2522Cable%2522%2540fq%253Dcircuitsloaded%253A%252226%2522&currentQuery=contactlayouttype%3AA%2B%2528same%2Bside%2529&origin=_l1stv13w>`__.

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**.
