Flexible peripheral modules for all your designs

Pmod™ devices are Digilent’s line of small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and embedded control boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective - near sensors and actuators.

Pmod modules communicate with system boards using 6, 8, or 12-pin connectors that can carry multiple digital control signals, including SPI and other serial protocols. Pmod modules allow for more effective designs by routing analog signals and power supplies only where they are needed, and away from digital controller boards.

Overview Pmod BLE

The Digilent Pmod BLE is a powerful peripheral module meant for use with any UART enabled development board. This Pmod employs the Roving Networks RN4870 to create a fully integrated Bluetooth Low Energy interface. This chip features an onboard Bluetooth stack that makes connecting and communicating with any Bluetooth 4.X device possible through simple UART commands. The RN4870 also features four built-in GATT services: Device Information, Airpatch, BeaconThings, and UART Transparent data streaming. It also allows up to five custom public services and up to four custom private services, each allowing up to eight custom characteristics. The Pmod BLE is an affordable, versatile, low energy addition to the wireless Pmod library.
