These connectors are hermaphroditic. Odd pin numbers on the module are connected to even pin numbers on the baseboard and vice versa.

3 x 4 modules use two  Samtec Razor Beam LSHM connectors on the bottom side.

When using the same type on baseboard, the mating height is 8mm. Other mating heights are possible by using connectors with a different height.
