The nRF52832 is an ultra low power System on Chip (SoC) from Nordic Semiconductor. It integrates the nRF52 series 2.4GHz transceiver, a 32 bits ARM® Cortextm-M4F CPU, Flash memory, analog and digital I/O. The nRF52832 supports Bluetooth Low Energy, ANT and proprietary protocols.
The IMM-NRF52832 is a 23 x 17 mm micro-module with embedded PCB antenna. It allows developers to take full advantage of the nRF52832 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.
