IMM-NRF52832-NANO Module

Video

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® Cortexm-M4F CPU, Flash memory, analog and digital I/O. The nRF52832 supports Bluetooth Low Energy, ANT and proprietary protocols.

Many modules on the market that claimed to be the smallest usually have missing components such crystal, inductor, antenna, limited I/O pins, etc... Components which are needed to add externally. The end results they still occupy a big chunk of space on the PCB. Contrary to those, the IMM-NRF52832-NANO is a nano size module that has everything built into a single package 10 x 7 x 1.6 mm, full 30 I/O pin. There is no extra component to add to take full advantage of the nRF52832 in low power Bluetooth 5 LE and all it's 30 I/O. The only space requires on your PCB is the module size itself. It is ideal for wearable and space constrained applications.

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 has instruction how to set up free Eclipse development tools.
