Nordic Semiconductor nRF51822 Bluetooth® Smart Beacon Kit is a reference design that lets you explore the full range of development possibilities for beacons using Bluetooth Smart technology. It consists of a complete hardware and software solution that when used with our nRF Beacon App (available for both iOS v4.1 and Android v4.3), gives you everything required for designing a comprehensive beacon system.

It is ultra-compact at 20 mm in diameter and can run from CR1632 coin-cell batteries. The kit has two buttons which can be programmed to enable easy switching between modes and/or functionality, as well as an RGB LED which can be configured to indicate different events. Ten GPIO pins are available for expansion and the kit can be connected to an external programmer/debugger during development work. The nRF51822 Bluetooth Smart Beacon Kit also supports complete Over-The-Air (OTA) Device Firmware Upgrade (DFU) for all firmware on the nRF51822 chip.
