STEVAL-STWINKT1B, STWIN SensorTile Wireless Industrial Node Development Kit and Reference Design for Industrial IoT Applications Description The STWIN SensorTile Wireless Industrial Node (STEVAL-STWINKT1B) is a development kit and reference design that simplifies prototyping and testing of advanced industrial IoT applications such as condition monitoring and predictive maintenance. The kit includes a core system board with a suite of embedded industrial-grade sensors and an ultra-low-power microcontroller for vibration analysis of 9-DoF motion measurement data over a wide range of vibration frequencies, including very high-frequency audio and ultrasound spectra, as well as high-precision local temperature and environmental monitoring. The development kit is complemented by a comprehensive set of software packages and optimized firmware libraries, as well as a cloud dashboard application, all of which help accelerate development cycles for end-to-end solutions. The kit supports Bluetooth® Low Energy wireless connectivity through an onboard module and Wi-Fi connectivity through a dedicated plug-in expansion board (STEVAL-STWINWFV1). Wired connectivity is also supported through an on-board RS485 transceiver. The core system board also includes an STMod+ connector for compatible, low-cost, small form factor daughter boards connected to the STM32 family, such as the LTE Cell Pack. In addition to the Core System Board, the kit comes with a 480 mAh Li-Po battery, an STLINK-V3MINI debugger, and a plastic box.
