ST公司的STEVAL-STLKT01V1 SensorTile开发套件支持和扩展SensorTile传感器模块(13.5mm x 13.5mm),它包括MEMS加速度计,陀螺仪,磁力计,压力传感器和MEMS麦克风.开发板采用低功耗80 MHz STM32L476JGY微控制器来检测和低功耗蓝牙连接到集线器,以开发可穿戴设备,游戏附件,智能手机和物联网(IoT)设备.本文介绍了STEVAL-STLKT01V1主要特性和功能框图,以及套件中的STLCS01V1 SensorTile板,STLCR01V1 SensorTile板和STLCX01V1 SensorTile板主要特性,电路图和材料清单.

 The STEVAL-STLKT01V1 is a comprehensive development kit designed to support and expand the capabilities of the SensorTile and comes with a set of cradle boards enabling hardware scalability. The development kit simplifies prototyping, evaluation and development of innovative solutions. It is complemented with software, firmware libraries and tools, including a dedicated App.

The SensorTile is a tiny, square-shaped IoT module that packs powerful processing capabilities leveraging an 80 MHz STM32L476JGY microcontroller and Bluetooth low energy connectivity based on BlueNRG network processor as well as a wide spectrum of motion and environmental MEMS sensors, including a digital microphone.

SensorTile can fit snugly in your IoT hub or sensor network node and become the core of your solution.
