The OAK-SoM (BW1099) is a System on Module (SoM) designed for integration into top-level system with a need for a low-power, 4 Tera Operation Per Second (TOPS) AI vision system. To be used in industrial automation, robotics and security systems. The OAK-SoM interfaces with the system through a single 10-Gbps-rated 100-pin board-to-board mezzanine connector which carries all signal I/O as well as 5v input. The on-board SMPS system regulates the 5V input and provides all necessary digital and analog power. An auxiliary power port is offered to interface without connection to a baseboard.
Devices that use OAK-SoM¶
All devices that have SoM on-board are also open-source. You could redesign them, for example to change stereo baseline. If you are interested in integrating DepthAI (via SoM) into your product, see documentation here.
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
Object tracking: 2D and 3D tracking with ObjectTracker node

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.
The maximum operating ambient temperature of RVC2 based devices is between 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).
