Pmod interface (or Peripheral Module interface) is an open standard defined by Digilent Inc in the Digilent Pmod Interface Specification[1] for peripherals used with FPGAs or microcontrollers development boards. The AXIOM Beta Single PMOD Plugin Module features PMOD debug inputs/outputs for connecting a wide range of external PMOD devices - mainly intended for development and testing when general purpose Input/Output (GPIO) is required.
