Multi-sensor Module Speeds IoT And Wearable Designs


STMicroelectronics has launched a new 13.5mm x 13.5mm multi-Sensor module which can be used as a sensing and connectivity hub for developing products such as wearables, gaming accessories, and smart-home or Internet-of-Things (IoT) devices

Based on a low-power STM32L4 microcontroller, SensorTile contains a MEMS accelerometer, gyroscope, magnetometer, pressure sensor, a MEMS microphone.

The board features a complete Bluetooth Low-Energy transceiver which enables streaming inertial, audio, and environmental data to ST’s BlueMS smartphone app that can be downloaded free of charge from popular app stores.

To speed software development, ST offers APIs based on the STM32Cube Hardware Abstraction Layer and middleware components, including the STM32 Open Development Environment. Many example programs including software for position sensing, activity recognition, and low-power voice communication, are also offered.


The complete kit includes a cradle board, which carries the 13.5mm x 13.5mm SensorTile core system in standalone or hub mode and can be used as a reference design. This board contains a humidity and temperature sensor, a micro-SD card socket, as well as a lithium-polymer battery (LiPo) charger.

A LiPo rechargeable battery and a plastic case provides a convenient housing for the cradle, SensorTile, and battery combination.

A cradle/expansion board with an analog audio output, a micro-USB connector, and an Arduino-like interface can be plugged into any STM32 Nucleo board to expand developers’ options for system and software development. A programming cable is also included.

The SensorTile kit (STEVAL-STLKT01V1) is available now from distributors or can be purchased directly from, priced at $89.00.
