The MXM314 connector has different pin number than one in Captain Edge V12. The Edge schematics number pins starting with P1/S1, however the MXM3 starts with E1 pins and then alternates odd and even numbers on the connector. What is the mapping to be used between MXM3 numbering and Edge schematics?
You can check the below PCB design file(only with MXM3 and mounting screws) for the further information:
