Getting started with the STEVAL-STWINBX1 SensorTile wireless industrial node
Introduction
The STWIN.box (STEVAL-STWINBX1) is a development kit and reference design that simplifies prototyping and testing of
advanced industrial sensing applications in IoT contexts such as condition monitoring and predictive maintenance.
It is an evolution of the original STWIN kit (STEVAL-STWINKT1B) and features a higher mechanical accuracy in the
measurement of vibrations, an improved robustness, an updated BoM to reflect the latest and best-in-class MCU and industrial
sensors, and an easy-to-use interface for external add-ons.
The
STWIN.box
kit consists of an STWIN.box core system, a 480mAh LiPo battery, an adapter for the
plastic case, an adapter board for DIL 24 sensors and a flexible cable.
The many on-board industrial-grade sensors and the ultra-low power MCU enable applications that feature: ultra-low power,
9 DoF motion sensing, wide-bandwidth vibration analysis, audio and ultrasound acoustic inspection, very precise local
temperature, and environmental monitoring.
A rich set of software packages is available in source code. Optimized firmware libraries and a complete companion cloud
application help to speed up the design cycle to develop end-to-end solutions.
The kit supports a broad range of connectivity options, including the built-in RS485 transceiver, BLE, Wi-Fi, and NFC.
The
STWIN.box
also includes a 34-pin expansion connector for small form factor daughter boards associated with the STM32
family, such as the
STEVAL-C34KAT1
The
STWIN.box
is suitable for field trials, demonstrations, and PoC for industrial IoT applications that use ST software and
third-party software.
