OAK-FFC-6P kit

Overview

The OAK-FFC-6P baseboard has 6 FFC interfaces which allows for six 2-lane MIPI camera modules. It is the first device from OAK Series 3 (with RVP3) and uses the OAK-SoM-Max.

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 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.

RVC3 inside

This OAK device is built on top of the RVC3. Main features:

Key features

  • 6x 2-line MIPI camera interfaces (all of the CCMs supported in DepthAI can run on 2-lane MIPI, most of them also in full resolution)

  • OAK-SoM-Max connected to the baseboard

  • 5V power input via barrel jack

  • USB 3.1 Gen 1 Type-C

  • IMU support (BMI270 by default, footprint for BNO086)

  • uSD card slot

  • Onboard EEPROM

  • Pads for DepthAI SoM 1.8V SPI

  • Pads for DepthAI SoM 1.8V Aux Signals (I2C, UART, GPIO)

  • PSRBS connector (5V, STROBE, RST, BOOT_SEL, FSIN_ALL, FSIN_STEREO)

  • 1025 coin battery holder

  • Design files produced with Altium Designer 22

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-6P 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-Max, total power consumption usually stays below the 1.5 A specification, Type-C power of 1.5 A or greater is recommended.

Interfacing with the OAK-SoM-Max is also possible with OAK-FFC-6P connector pads QSPI, and AUX. These pads are designed for the Amphenol/FCI 20021121-00010T1LF or equivalent. Please refer to the schematics for pinout information.

The reset button soft resets the Luxonis DepthAI SoM only, SYS-RST button resets the power system of the DepthAI and PWR button is a GPIO button that can be used to turn off/on the SoM. BOOT button is meant to be used only for recovery purposes changing GPIO boot mode to eMMC recovery when the button is held on system power up.

The PG LED indicates 5V power is present and all outputs of the DC-DC converters are inside the specified nominal voltages. The LED1 indicates “BOOT” status of the DepthAI SoM. The LED2 is an “CONNECT” status LED which indicates that the OAK-SoM-Max is connected to the network/device.

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.
