OAK-D¶
Overview¶
The OAK-D baseboard has three on-board cameras which implement stereo and RGB vision, piped directly into the OAK SoM for depth and AI processing. The data is then output to a host via USB 3.1 Gen1 (Type-C).
Hardware specifications¶
This OAK camera uses USB-C cable for communication and power. It supports both USB2 and USB3 (5Gbps / 10Gbps).

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
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.
OAK-D PCBA¶
Available despite decreasing demand, OAK-D PCBA is essentially an OAK-D without an enclosure and instead has a heatsink. This could still be useful for some applications where size/weight is really critical (eg. drones), and PCBA also exposes some additional connectors.
Getting started¶
The OAK-D is powered via USB Type-C or from a 5V, 5.5m x 2.5mm barrel jack. USB3 5Gbps speeds are standard for streaming video or data from the device. With cameras and the OAK-SoM, 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-D connector pads J4, J5, and J6. These pads are designed for the Amphenol/FCI 20021121-00010T1LF or equivalent. Please refer to the schematics for pinout information.
The reset button is not populated by default on the OAK-D, but can be added. Alternatively, the OAK-SoM can be reset by shorting RST to ground.
The 5V LED indicates 5V power is present on the PCBA. The PG LED indicates “power good” from the OAK-SoM. The “RUN” LED indicates that the OAK-SoM is not in reset.
Power consumption¶
Most of the power is consumed by the RVC2, so the power consumption mostly depends on the workload of the VPU:
Base consumption + camera streaming: 2.5W - 3W
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 ~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).
