The main board includes the STM32WB5MMG ultra-low-power and small form

factor wireless radio module. This module is FCC and IC certified (FCC ID:

YCP-STM32WB5M001 and IC: 8976A-STM32WB5M01). It is based on the

STM32WB55VGY wireless SoC, compliant with the Bluetooth® Low Energy SIG

specification v5.2, ZigBee 3.0, and IEEE 802.15.4-2011.

The powerful Arm®-based Cortex-M4 with FPU and large memory allows running the

embedded algorithm at node level.

The multiprotocol support ensures the development of applications with different

types of connectivity, using a unique hardware. Moreover, the main board integrates

the STSAFE-A110 secure element that provides authentication and secure data

management services to a local or remote host.

The IIS3DWB high bandwidth (up to 6 kHz) accelerometer, the IIS2DLPC ultra-low

power, and the ISM330DHCX inertial module (accelerometer and gyroscope) with

MLC make the hardware ideal for a customized vibration monitoring development.

The STTS22H high accuracy temperature sensor has been integrated in the board,

far from the heat noise sources (the power management and the microcontroller) to

provide a more precise temperature measurement. Its exposed pad sensor feature

allows the temperature sensor to be in contact with the surface target equipment.

An on-board external memory is connected via QSPI to the STM32WB5MMG module

for data buffering and event storage.

The STEVAL-PROTEUS is LiPo rechargeable battery-powered. It can also be

powered via USB (5 V at 500 mA) or via a primary battery (which is not included

in the kit).

The power management features the ST1PS02 400 mA step down converter for

low-power applications and the STBC02 for battery charging.

An application example firmware with dedicated algorithms is preloaded in the

STM32WB5MMG flash memory for easy demonstration of wireless vibration and

temperature node monitoring.
