The ANT/BLE RGB beacon is designed for engineers looking to develop with ANT+ or BLE 2.4GHz radio protocols. It features a fully programmable Nordic nRF51422 System On Chip which allows developers fully access to the ARM Cortex‐M0 core to use it standalone, or add ANT+, BLE or concurrent ANT+ and BLE firmware stacks.

An ultra low power LIS2DH 3‐axis accelerometer adds acceleration data and the nRF51422 includes a built‐in temperature sensor. The sensor port supplies GND, two dedicated digital IOs, and one configurable digital IO/Vcc line. All segments in the eight RGB LED array are direct‐driven to minimize driver complexity and allow glitch‐less persistence of vision (PoV) applications.
