According to Qseven

Printed circuit of the board is made of ten layers, some of them are ground planes, for

disturbance rejection.

The MXM connector accommodates various connector heights for different carrier board

applications needs. Qseven

specification suggests two connector heights, 7.8mm and

7.5mm, but it is also possible to use different connector heights, also remaining compliant

to the standard.

When using different connector heights, please consider that, according to Qseven

specifications, components placed on bottom side of Q7-928 will have a maximum height

of 2.2mm ± 0.1. Keep this value in mind when choosing the MXM connector's height, if it is
