According to SMARC Rel 2.1 specification, all interface signals are reported on the card edge connector, which is a 314-pin Card Edge that can be inserted into
standard low profile 314 pin 0.5mm right pitch angle connector that was originally defined for use with MXM3 graphics cards.
Not all signals contemplated in the SMARC Rel 2.1 are implemented on card edge connector, therefore, please refer to the following table for a list of effective signals
