Introduction
The STEVAL-WESU1 is a System Evaluation Board designed to provide a cost effective solution
for precise motion sensing in wearable applications. The system is featuring a low power ARM
Cortex-M3 microcontroller unit (STM32L151), an iNEMO inertial module (LSM6DS3), a high
performance magnetometer (LIS3MDL), a barometric pressure sensor (LPS25HB), a Bluetooth®
low energy wireless network processor (BLUENRG-MS) and power management circuitry that
allows fast charging and precise energy estimation (STNS01 and STC3115). The connectivity
granted by the best in class BLUENRG-MS and supported by the integrated balun (BALF-NRG-
01D3) permit to maximize the RF performances with low area occupancy and design effort and
pass the RF Test for FCC certification (FCC ID: S9NWESU1) and IC certification (IC ID: 8976C-
WESU1).
An Android and iOS APP, available on Google Play and Apple Store, can be used for displaying
information sent by the STEVAL-WESU1 through BLE connectivity as well as for setting operative
modes.
