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

FP-SNS-DATALOG2

Software Overview

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
