STEVAL-STWINBX1 [STMicroelectronics]

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 bill of materials (BOM) to reflect the latest and best-in-class microcontroller unit (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 ST-LINK debugger, a 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, nine 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. For wired connectivity, it includes a USB Type-C® port that can be used for power supply, data transfer and STM32 programming via DFU, and an RS-485 transceiver. For wireless connectivity, the kit offers Bluetooth® Low Energy, Wi-Fi, and NFC options.

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, STEVAL-C34KAT2 and STEVAL-PDETECT1 expansion boards.

The STWIN.box is suitable for field trials, demonstrations, and proof of concept for industrial IoT applications that use ST software and third-party software.
