SMARC Connector
According to SMARC Rel. 2.1.1 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 SMARC
®
standard are implemented on MXM3 connector, due to the functionalities really implemented on SM-B79.
Therefore, please refer to the following table for a list of effective signals reported on MXM3
(if specifically written) are referred to the SMARC
®
module, i.e. they are inputs and outputs of the module itself, not of the carrier board (where they are, respectively,
outputs and inputs).
