Overview

The OAK-SoM-Pro is a System on Module (SoM) designed for integration into top-level systems with a need for a low-power, high performance, real-time AI, and depth perception. It is ideal for use in industrial automation, robotics, and security systems. The OAK-SoM-Pro interfaces with the system through two 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.

OAK-SoM-Pro comes in two variants: Robotics Vision Core 2 based and Robotics Vision Core 3 based SoM. Robotics Vision Core 3 provides quadcore ARM CPU, INT8 quantization, and enchanced stereo depth perception compared to the Robotics Vision Core 2.

OAK-SoM-Pro-S3 (Robotics Vision Core 3) was designed to be a drop-in replacement for OAK cameras that use OAK-SoM-Pro (Robotics Vision Core 2) (list below).

Devices that use OAK-SoM-Pro MX

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.

Robotics Vision Core 2 inside:

This OAK device is built on top of the RVC2. Main features:

../_images/board-back.png

OAK-SoM-Pro-S3 has an Robotics Vision Core 3 and quadcore ARM CPU on board. It was designed to have the same dimensions and pinout as the OAK-SoM-Pro, so it can easily replace the OAK-SoM-Pro on OAK cameras that use it (list here).

It was primarily designed for evaluation and backwards compatibility. For new products, we would suggest using OAK-SoM-Max (differences below).

RVC3 inside

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

OAK-SoM-Pro-S3 vs OAK-SoM-Max

These are both our inital SoMs that have on-board Robotics Vision Core 3 (Robotics Vision Core 3). The OAK-SoM-Pro-S3 was desgined first for evaluation and backwards compatibility with the OAK-SoM-Pro. The OAK-SoM-Max was designed later for maximum performance and extensibility.

  • Compatiblity with existing models
  • Connectors
    • Pro-S3 has 2x 100-pin mezzanine connector, with the exact same pinout as SoM-Pro.

    • Max has 3x 100-pin mezzanine connector, which exposes additional MIPI RX/TX lines.

  • MIPI lines
    • Pro-S3 has 2x 4-lane and 2x 2-lane MIPI RX lines.

    • Max has 6x 2-lane MIPI RX and 2x 2-lane, 1x 4-lane MIPI TX lines.

  • RAM
    • Pro-S3 has 1x DDR RAM due to size/shape constraints, even though Robotics Vision Core 3 supports dual channel RAM.

    • Max has 2x DDR RAM on-board, which provides maximum performance, as Robotics Vision Core 3 supports dual channel RAM.

  • Size
    • Pro-S3: 30mm x 45mm

    • Max: 40mm x 40mm
