## Description

Bluetooth 4.0 beacon based on NRF51822 for proximity identification and location in iBeacon, smart home, wearable or tracking applications. It operates at 2-3.3V with CR2032 battery, has ultra low standby consumption for long autonomy, integrated PCB antenna and communication range of up to 30 m in open space.
The NRF51822 module is a highly energy-efficient wireless Bluetooth 4.0 Beacon device ideal for a wide variety of applications, including iBeacon systems, wearables, electronic games, and smart home control.
Thanks to the BEacon technology used, it can be used for localization within the range of the signal.
Its firmware also meets Apple's iBeacon technical standards. Due to the low supply voltage, from 2.0 to 3.3V, and the low current consumption in sleep mode (only 3.1uA), the module is an optimal solution for devices that require a long battery life.
This module requires a CR2032 coin cell battery to operate.
