STWIN development kit - STEVAL-STWINKT1B
Hardware Overview
STWIN - SensorTile Wireless Industrial Node
The STWIN (STEVAL-STWINKT1B) is a development kit and reference design that simplifies prototyping and testing
of advanced industrial IoT applications such as condition monitoring and predictive maintenance. The kit supports
BLE wireless connectivity through an on-board module and Wi-Fi connectivity through a special plugin expansion
board (STEVAL-STWINWFV1), wired RS485 and USB OTG connectivity.
Key Features
•Multi-sensing wireless platform implementing vibration monitoring and ultrasound detection
•Updated version of STEVAL-STWINKT1, now including STSAFE-A110 populated, BlueNRG-M2S module and
IMP23ABSU MEMS microphone
•Ultra-low-power ARM Cortex-M4 MCU at 120 MHz with FPU, 2048 kbytes Flash memory (STM32L4R9)
•Micro SD Card slot for standalone data logging applications
•Option to implement Authentication and Brand protection secure solution with STSAFE-A110
•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,
ultra-low-power high performance MEMS motion sensor (IIS2DH), ultra-low-power 3-axis magnetometer (IIS2MDC),
digital absolute pressure sensor (LPS22HH), relative humidity and temperature sensor (HTS221), low-voltage digital local
temperature sensor (STTS751), industrial grade digital MEMS microphone (IMP34DT05), analog MEMS microphone with
frequency response up to 80 kHz (IMP23ABSU)
•Modular architecture, expandable via on-board connectors: STMOD+ and 40-pin flex general purpose expansions, 12-pin
male plug for connectivity expansions, 12-pin female plug for sensing expansions
•Other kit components: Li-Po battery 480 mAh, STLINK-V3MINI debugger with programming cable, Plastic box

FP-AI-PREDMNT2 Software Description
FP-AI-PREDMNT2 is an STM32Cube function pack that programs the STWIN as an
IoT Edge node, connected to the cloud, able to acquire sensor data, process them and
send the results to the DSH-PREDMNT cloud dashboard. It includes dedicated
algorithms for advanced time and frequency domain signal processing and analysis of
3D digital accelerometers with flat bandwidth up to 6 kHz.
Key features
•Compatible with NanoEdge™ AI Studio solution from Cartesiam, to enable AI-
based solution (NanoEdge™ AI library generation is out of the scope of this
function pack and must be generated using NanoEdge™ AI Studio)
•Generic FFT library middleware to enable frequency domain analysis for any kind
of sensor through Fast Fourier Transform (with programmable size, overlapping
and windowing)
•Motion TD library middleware for vibration analysis in time domain (speed RMS
and acceleration peak)
•Configurable alarm and warning thresholds for key parameters
•Compatible with STBLESensor application forAndroid/iOS, to perform Wi-Fi
configuration and secure certificate provisioning
•Compatible with DSH-PREDMNT web-based predictive maintenance dashboard
for monitoring sensor data and device status
•Easy portability across different MCU families, thanks to STM32Cube
•Firmware modular example based on eLooM (embedded Light object-oriented
fraMework for STM32) to enable code re-usability at application level
•Free, user-friendly license terms
