3.7.2 SOM Block Diagram

The Open-Q 820 SOM measuring 42mm x 82mm is where all the processing occurs. It is connected to the
carrier via a 314-pin MXM Gen-III edge connector. The purpose of this edge connector is to bring out
essential signals such that other peripherals can interface with the platform.
The SOM requires a board-to-board connector in addition to the MXM Gen III connector. This connector is
responsible for bringing out the audio signals to the carrier board whereas the MXM connector exposes all
other pin features supported by the SOC.
