IMM-NRF51422 Micro-Module

ANT & Bluetooth 4.0 Low Energy module, Beacon, Bluetooth Smart with builtin ARM Cortex-M0

The nRF51422 is an ultra low power System on Chip (SoC) from Nordic Semiconductor. It integrates the nRF51 series 2.4GHz transceiver, a 32 bits ARM® Cortextm-M0 CPU, Flash memory, analog and digital I/O. The nRF51422 supports ANT, Bluetooth Low Energy and proprietary protocols.

The IMM-NRF51422 is a 23 x 17 mm micro-module with embedded PCB antenna. It allows developers to take full advantage of the nRF51422 by making all its I/O available via 35 SMD/Through hole 1.27mm pitch pads. The module can be mounted with header pins in order to re-use during development and prototyping phase and SMD it for production to be the most cost effective. It is designed to be easily hand soldered which makes this a perfect choice for quick prototyping and hobbyist as well as production ready.

Many examples source code, including iOS & Android, are available here http://embeddedsoftdev.blogspot.ca/p/ehal-nrf51.html and the Nordic SDK. The blog site also have instruction how to setup free Eclipse development tools.
