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
please refer to the following table for a list of effective signals reported on MXM connector.
Furthermore, many signals available on the card edge connector can be used to implement different functionalities, by exploiting the pin-muxing functionalities offered
by NXP i.MX8M Mini and i.MX8M Nano processors.
For accurate signals description, please consult the following paragraphs. In the first instance, the signals with exclusive functionality will be described thoroughly.
After them, it will be given a table with a complete list of all pins with all possible alternative functionalities.
NOTE: Even pins are available on top side of CPU board; odd pins are available on bottom side of CPU board. Please refer to board photos.
