The ATULPC-DEMO demo uses Atmel’s SAM L21 MCU, interfaced with BTLC1000 fully certified module and several sensors on a small form factor PCB (40mm X 30mm) operated on a coin cell battery. The environment sensor data (temperature, pressure, humidity, light), motion sensor data (3-axis acceleration, gyroscope) and sensor fusion data (3D plot, step count, free fall detection) are sent using BLE and displayed on an Android App. The HMI interface of the App is linked to a touch surface of the demo board, which is driven by the Peripheral Touch Controller integrated in the SAML21 MCU.

The User Guide & Schemattic of the demonstrator platform is located on the documents tab. You will also find additional downloads, including design files, firmware & mobile app source code, at the bottom of this page. The android app can also be downloaded from the Google Play store.
