OAK-FFC 1P PoE¶
Overview¶
The OAK-FFC 1P PoE offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds, along with user-selectable external power from a 5V barrel jack. The Luxonis OAK-FFC-IMX378 12MP RGB camera module can be connected via the 26-pin FFC interface, which exposes a 4-lane MIPI CSI-2 channel directly into the Robotics Vision Core 2 (RVC2) on the OAK-SoM-Pro (System on Module) for processing. Data can also be streamed to a host via USB 3.1 Gen1 (Type-C). Finally, the PoE Board exposes boot selection switches, allowing the end user to boot the OAK-SoM-Pro from USB or the on-board eMMC or NOR flash.
Note
The OAK-FFC 4P PoE offers the same functionality as the OAK-FFC 1P PoE, but also 3 additional FFC ports and PoE passthrough feature (for daisy chaining).
RVC2 inside¶
This OAK device is built on top of the RVC2. Main features:
4 TOPS of processing power (1.4 TOPS for AI - RVC2 NN Performance)
Run any AI model, even custom-architectured/built ones - models need to be converted.
Encoding: H.264, H.265, MJPEG
Computer vision: warp/dewarp, resize, crop via ImageManip node, edge detection, feature tracking. You can also run custom CV functions
Stereo depth perception with filtering, post-processing, RGB-depth alignment, and high configurability
Object tracking: 2D and 3D tracking with ObjectTracker node

Getting started¶
Note
For more information on how to start with POE devices, check our guide Getting started with OAK PoE devices.
This OAK PoE camera accepts power input from he 802.3af, Class 3 PoE circuitry. It can also accect power through the on-board USB C connector - which is not exposed through the enclosure, so enclosure needs to be removed.
Booting can be accomplished from either the USB interface or from the eMMC or NOR flash on the OAK-SoM-Pro, and boot selection is configured with the DIP switch bank near the USB connector.
Interfacing with the OAK-SoM-Pro is also possible with PoE Board connector pads J5 and J8, which expose OAK-SoM-Pro auxiliary I/O and BW2099 Quad SPI, respectively. These headers are Amphenol/FCI 20021121-00010T1LF or equivalent. Please refer to the schematics for pinout information.
The reset button resets the OAK-SoM-Pro only.
The 5V LED indicates 5V power is present on the BW2098POE.
The PG LED indicates “power good” from the OAK-SoM-Pro.
The “RUN” LED indicates that the OAK-SoM-Pro is not in reset.
Caution should be taken when handling any PoE circuit board. Do not directly touch the circuitry as potentials up to and exceeding 57V may exist. Always use electronics handling best practices.
Power consumption¶
Most of the power is consumed by the RVC2, so the power consumption mostly depends on the workload of the chip:
Base consumption + PoE circuitry + camera streaming: 3W - 3.5W
AI subsystem consumption: Up to 1W
Stereo depth pipeline subsystem: Up to 0.5W
Video Encoder subsystem: Up to 0.5W
So the total power consumption can be up to ~5.5W if you are using all the features at 100% at the same time. To reduce the power consumption, you can reduce FPS of the whole pipeline - that way, subsystems won’t be utilized at 100% and will consume less power.
Operating temperature¶
The ambient operating temperature of RVC2 based devices is between -20°C and 50°C when fully utilizing the VPU.
Similarly to the Power consumption, max operating temperature depends on VPU utilization. The higher the VPU utilization, the more heat the VPU will generate. The RVC2 VPU can continuously operate at 105 °C, after which the depthai library will automatically shut down the device (to avoid chip damage).
