STEVAL-STWBXCS1
STWIN.box development kit - STEVAL-STWINBX1
Hardware Overview
STWIN.box - SensorTile Wireless Industrial Node
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 ST-LINK
debugger (STEVAL-MKIGIBV4), a plastic case, an adapter board for DIL 24 sensors and a flexible cable.
Key Features
•Multi-sensing wireless platform for vibration monitoring and ultrasound detection
•Built around STWIN.box core system board with processing, sensing, connectivity, and expansion capabilities
•Ultra-low power Arm® Cortex®-M33 with FPU and TrustZone at 160 MHz, 2048 kBytes Flash memory (STM32U585AI)
•MicroSD card slot for standalone data logging applications
•On-board Bluetooth® low energy v5.0 wireless technology (BlueNRG-M2), Wi-Fi (EMW3080) and NFC (ST25DV04K)
•Wide range of industrial IoT sensors: Ultra-wide bandwidth (up to 6 kHz), low-noise, 3-axis digital vibration sensor (IIS3DWB),
3D accelerometer + 3D gyro iNEMO inertial measurement unit (ISM330DHCX) with Machine Learning Core, High-
performance ultra-low-power 3-axis accelerometer for industrial applications (IIS2DLPC), Ultra-low power 3-axis
magnetometer (IIS2MDC), Dual full-scale, 1.26 bar and 4 bar, absolute digital output barometer in full-mold package
(ILPS22QS), Low-voltage, ultra low-power, 0.5°C accuracy I²C/SMBus 3.0 temperature sensor (STTS22H), Industrial grade
digital MEMS microphone (IMP34DT05), Analog MEMS microphone with frequency response up to 80 kHz (IMP23ABSU)
•Expandable via a 34-pin FPC connector

Software Description
The FP-SNS-DATALOG2 function pack for STEVAL-STWINBX1 represents an
evolution of FP-SNS-DATALOG1 and provides a comprehensive solution for saving
data from any combination of sensors and microphones configured up to the
maximum sampling rate.. It natively supports STEVAL-STWINBX1 with its external
addons (STEVAL-C34KAT1, STEVAL-C34DIL24).
The package also includes an example of ultrasound condition monitoring
(UltrasoundFFT) that calculates the FFT of the IMP23ABSU analog microphone
signal and streams the result to aPC GUI via USB.
Key features
•High-rate (up to 6 Mbit/s) data capture software suite:
•Dedicated Python SDK, ready-to-use for integration into any data science design flow
•Compatible with ST BLESensor app for system setup and real-time control
•Allow to setup MLC (Machine Learning Core) or ISPU (Intelligent Sensor Processing Unit)
•Synchronized timestamping and labelling mechanisms common to all sensors
•Generic FFT library middleware to enable frequency domain analysis
•Firmware modular examples based on eLooM (Embedded Light Object Oriented
framework for STM32) to enable code reusability at application level
•Based on STM32Cube software development environment for STM32
microcontrollers
•Based on AzureRTOS
