Overview

OAK-SoM-Max has on-board Robotics Vision Core 3, which has much greater AI performance compared to Robotics Vision Core 2, and quadcore ARM CPU. The OAK-SoM-Max is a System on Module (SoM) designed for integration into top-level system with a need for a low-power, high performance, real-time AI and depth perception.

The OAK-SoM-Max interfaces with the system through three 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.

Devices that use OAK-SoM-Max

All devices that have SoM on-board are also open-source. If you are interested in integrating DepthAI (via SoM) into your product, see documentation here.

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.

OAK SoM differences

  • 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

OAK-SoM-Max variants

We offer 3 variants of the OAK-SoM-Max which expose a different configuration of MIPI connectivity:

  • OAK-SoM-Max - 6x 2-lane MIPI. This is the default configuration

  • OAK-SoM-Max-1 - 4x 2-lane MIPI, 1x 4-lane MIPI. RX0+RX1 are merged into a single 4-lane MIPI

  • OAK-SoM-Max-2 - 2x 2-lane MIPI, 2x 4-lane MIPI. RX0+RX1 and RX4+RX5 are merged into 4-lane MIPI
