====== uSomIQ mainboard connectors pins ======
This the description of signals arranged on the uSomIQ side and its connectors P2 and P3. A baseboard connectors will have the same signals but with different numbering. For instance, pin1 of P2 on the module connects to pin2 of the baseboard connector, pin2 of P2 on the module connects to pin4 of the baseboard connector etc.
