Pmod Connectors

Pmod connectors are 2x6 right-angle, 100-mil female connectors that mate with standard 2x6 pin

headers available from a variety of catalog distributors. Each 12-pin Pmod connector provides two

3.3V VCC signals (pins 6 and 12), two Ground signals (pins 5 and 11), and eight logic signals. VCC

and Ground pins can deliver up to 1A of current. Pmod data signals are not matched pairs, and they

are routed using best-available tracks without impedance control or delay matching.

Digilent produces a large collection of Pmod accessory boards that can attach to the Pmod and

VHDC expansion connectors to add ready-made functions like A/D’s, D/A’s, motor drivers, sensors,

cameras and other functions. See www.digilentinc.com for more information.
