Pmod Interface

Pmod interface (peripheral module interface) is an open standard defined by Digilent in the Pmod Interface Specification[1] for connecting peripheral modules to FPGA and microcontroller development boards.

Overview

Modules are available from simple push buttons to more complex modules with network interfaces, analog to digital converters or LCD displays. These modules can be used with a variety of FPGA or microcontroller development boards from different vendors. Pmods are not necessarily plug-and-play - software and configuration is required - but the hardware interface is pre-designed and modules can be quickly assembled with host boards for prototyping or evaluation purposes with no soldering required.

Pmods come in a standard 6-pin interface with 4 signals, one ground and one power pin. Double and quad Pmods also exist. These duplicate the standard interface to allow more signals to pass through to the module.

Pmods can use either SPI, I2C or UART protocol. With I2C it is possible to use a 4-pin connector. Alternatively the pins 1 to 4 can be used as simple digital I/O pins.

History

Digilent was founded in 2000 by two Washington State University electrical engineering professors.[2]

In 2011, v1.0.0 of Pmod Interface Specification was released.[3]

In January 2013, National Instruments acquired all outstanding shares of Digilent Inc., which became a wholly owned subsidiary.[4]
