Pmod™ is the Digilent defined standard of Peripheral Modules, small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and microcontroller boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective - near sensors and actuators.
Pmods communicate with host boards using 6, 8 or 12-pin connectors that can carry multiple digital control signals, taking advantage of standard serial protocols such as SPI and I²C. Pmods allow for more effective designs by routing analog signals and power supplies only where they are needed and away from digital controller boards.
Pmods are designed to plug directly into Pmod host ports that adhere to the Digilent Pmod Interface Specification. Additionally, the Digilent Pmod Standard lays out guidelines for form factor, communication protocols and access to a target audience through reference manuals, code examples, user guides, and technical support.
