120-Pin Connector

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 email address is being protected from spambots. You need JavaScript enabled to view it. to discuss alternatives.
