OAK-SoM-Max has on-board Keem Bay VPU, which has much greater AI performance compared to Myriad X, 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.
OAK-SoM-Pro-KB vs OAK-SoM-Max¶
These are both our inital SoMs that have on-board Keem Bay VPU. The OAK-SoM-Pro-KB 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¶
Pro-KB 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-KB 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.
Pro-KB has 1x DDR RAM due to size/shape constraints, even though Keem Bay VPU supports dual channel RAM.
Max has 2x DDR RAM on-board, which provides maximum performance, as Keem Bay VPU supports dual channel RAM.
