The 120-pin MOLEX connector is used either by a 120-pin expansion board (e.g. netmicroSD-vx ) or by a custom-made board.
The mating connector from MOLEX that belongs on the daughtercard side is #54876-1274.
7/25/08: As Molex is phasing out this connector, Gumstix has secured a limited supply. As such, customers planning a verdex-based product should contact This e-mail address is being protected from spambots. You need JavaScript enabled to view it to discuss alternatives.

Notes: (1) Schematic images and charts below are from the point of view of the gumstix verdex. Looking at the connector from the daughtercard's point of view, these signals are mirrored.
