The I-SYST IMM-NRF51822 is a 23 x 17 mm micro-module with embedded PCB antenna. It allows developers to take full advantage of the nRF51822 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. There is also a related IMM-NRF51422 (ANT & BLE micro-module Based on Nordic NRF51422 SoC) module. 
The Nordic Semiconductor nRF51822 is an ultra low power System on Chip (SoC). It integrates the nRF51 series 2.4GHz transceiver, a 32 bits ARM® Cortextm-M0 CPU, Flash memory, analog and digital I/O. The nRF51822 supports both Bluetooth Low Energy and proprietary protocols.
