The STWIN.box (STEVAL-STWINBX1) is a development kit and reference design that simplifies prototyping and testing of industrial sensing applications in IoT applications 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 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 vibrometer and temperature sensors expansion board. The STWIN.box is suitable for field trials, demonstrations, and PoC for industrial IoT applications that use ST software and third-party software.

What’s in the Kit?
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.

Electronic circuits form a mostly invisible part of the world we live in today. These circuits are present in microchips or just “chips”, which combine the latest advances in performance, intelligence and, efficiency. Hundreds or thousands of these chips are integrated into each of the millions and billions of electronic devices people across the globe interact with every day. It is in this unseen realm that STMicroelectronics creates the sparks that animate the products we use at any given moment. Our technology is found everywhere microelectronics makes a positive contribution to people’s lives. Chips from ST embedding the most advanced innovations are an essential part of products as diverse as cars and key fobs, giant factory machines and data center power supplies, washing machines and hard disks, and smartphones and toothbrushes. We help our customers make these devices more intelligent, more energy efficient, more connected, safer and more secure. For more information, click here.
