OAK-SoM-Max¶
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
Pro-S3 is compatible with boards that have OAK-SoM-Pro integrated (list here). This allowed us for quicker evaluation of the new Robotics Vision Core 3.
Max is not yet compatible with any boards.
- 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
