Multi-sensor board speeds up wearable, IoT designs

STMicroelectronics has released a turnkey sensor board that provides a sensing and connectivity hub for wearables, gaming accessories, smart home, and IoT devices. For the sensing part, the 13.5 x 13.5-mm SensorTile module contains a MEMS accelerometer, gyroscope, magnetometer, pressure sensor, and MEMS microphone.

Then there is a low-power STM32L4 microcontroller and a Bluetooth low-energy (BLE) transceiver that also includes a miniature single-chip balun. A broad set of system interfaces is available to turn the module into a sensor fusion hub as well as a reference platform for firmware development.

The compact SensorTile board also comes with a microSD card socket and a lithium-polymer battery (LiPo) charger. Moreover, it's accompanied by a developer kit that includes a cradle/expansion board with an analog audio output, a micro-USB connector, and a programming cable.

Furthermore, the SensorTile kit features an Arduino-like interface, which can be plugged into any STM32 Nucleo board to expand design options for system and software development.

Developers can simply plug the multi-sensor module into a host board and power it immediately. It will start streaming inertial, audio, and environmental data to STMicro’s BlueMS smartphone app, which can be downloaded free of charge from popular app stores.
