According to Qseven
specifications, all interface signals are reported on the card edge connector, which is a 230-pin Card Edge that can be inserted into standard
230 pin MXM connectors, as described in Qseven
Not all signals contemplated in Qseven
Therefore, please refer to the following table for a list of effective signals reported on MXM connector. Please be aware that on signals' description, Input and Output
(if specifically written) are referred to the Qseven
outputs and inputs).
NOTE: Even pins are available on top side of Qseven
