STMicroelectronics Wearable Motion Sensor Motion Sensor Reference Design

The STEVAL-WESU1 reference design was developed and optimised with the latest technologies in wearable and portable applications.
The small size allows the hardware to be enclosed in a watch strap. You can experience and monitor the activity of a real motion and environmental sensor data in this acquisition system.
The ST WeSU app is a mobile application for the STEVAL-WESU1 evaluation board, which lets you manage all the board features and activate several application demos. Also found available free of charge from Apple Store and Google Play stores. The Apps are based on BlueST SDK, available on GitHub.
