BlueWear is a production ready 14.5mm x 13mm x 2.5mm form factor
device module for wearable and connected device applications. It features
STMicroelectronics BlueNRG-1, a very low power Bluetooth low energy
(BLE) single-mode network processer, and Cortex M0, application
processor, built on SoC (System-On-Chip).
BlueWear integrates a set of high value sensors on board, besides
providing ample IO pins and interfaces out of board for allowing
user to connect additional sensors and devices
