STMicroelectronics has announced SensorTile, which at 13.5mm x 13.5mm, the company claims is currently the smallest turnkey sensor board of its kind. It contains a MEMS accelerometer, gyroscope, magnetometer, pressure sensor and a MEMS microphone. With the on-board low-power STM32L4 microcontroller, it 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.
The module has a complete BlueTooth Low-Energy transceiver including a miniature single-chip on-board, as well as a broad set of system interfaces that support use as a sensor-fusion hub or as a platform for firmware development. It can be simply plugged into a host board, and when powered it immediately starts streaming inertial, audio and environmental data to ST’s BlueMS smartphone app that is available for free download.
Main features of the SensorTile core system:
- LSM6DSM 3D accelerometer + 3D gyroscope
- LSM303AGR 3D magnetometer + 3D accelerometer
- LPS22HB pressure sensor/barometer
- MP34DT04 digital MEMS microphone
- STM32L476 microcontroller
- BlueNRG-MS network processor with integrated 2.4GHz radio
