OAK-D-PoE¶
Overview¶
The OAK-D-PoE baseboard offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds. The OAK-D-POE baseboard has three on-board cameras which implement stereo and RGB vision, piped directly into the OAK-SoM-Pro for depth and AI processing. The data is then output to a host via USB 3.1 Gen1 (Type-C) or via 1000BASE-T ethernet connection. The OAK-D-POE board exposes boot selection switches, allowing the end user to boot the OAK-SoM-Pro module from USB or the on-board eMMC or NOR flash.
Hardware specifications¶
This OAK camera uses Power-over-Ethernet (PoE) for communication and power. It offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds (1 Gbps) and has a micro SD (uSD) card connector. A PoE injector/switch is required to power the device. It also features an IP67-rated enclosure.

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 - 4K/30FPS, 1080P/60FPS
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
Stereo depth perception¶
This OAK camera has a baseline of 7.5cm - the distance between the left and the right stereo camera. Minimal and maximal depth perception (MinZ and Max) depends on camera FOV, resolution, and baseline; more information here.
Ideal depth range: 70cm - 12m
MinZ: ~20cm (400P and extended), ~35cm (400P OR 800P, extended), ~70cm (800P)
Median depth accuracy (See 800P, 75mm baseline distance OAKs for details):
below 4m: below 2% absolute depth error
4m - 7m: below 4% absolute depth error
7m - 10m: below 6% absolute depth error
Integrated IMU¶
This OAK camera has an integrated BNO085, a 9-axis IMU (Inertial Measurement Unit). See IMU node for the API details on how to use it.
Note: due to supply chain issues, most of the OAK camera that were manufactured between Q2 2021 and Q2 2023 have integrated BMI270 - 6-axis IMU instead.
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).
To find out more, see our Operative temperature range documentation.
Vibration Testing¶
This OAK device has been tested for vibration tolerance according to the EN 60068-2-6:2008 standard:
Vibration Report - Report of the vibration stress tests performed by the SIQ (3rd-party lab)
Vibration Results - Results of Camera Focus, Camera Angles, and Stereo Depth Accuracy before and after the vibration stress tests
More information can be found at Vibration Tolerance documentation.
