STMicroelectronics STEVAL-PROTEUS1

Overview

STEVAL-PROTEUS1 from STMicroelectronics is an industrial sensor evaluation kit for condition monitoring, built around the STM32WB5MMG dual-core 2.4 GHz multiprotocol wireless SoC (Bluetooth® LE 5.2, IEEE 802.15.4, Zigbee 3.0, Thread), IIS3DWB 6 kHz vibration sensor, ISM330DHCX inertial module with machine learning core, STTS22H ±0.5°C temperature sensor, and STSAFE-A110 secure element - preconfigured for predictive maintenance prototyping.

For engineers reviewing the STEVAL-PROTEUS1 datasheet, STEVAL-PROTEUS1 pinout, STEVAL-PROTEUS1 application, or STEVAL-PROTEUS1 equivalent, this board supports time/frequency-domain vibration preprocessing, on-node AI inference via MLC/FSM, secure over-the-air firmware updates, and Android/iOS configuration via STBLESensor app - critical for industrial asset monitoring development.

Technical Context

The board implements a full-stack edge sensing node: the STM32WB5MMG executes real-time vibration analysis algorithms (FFT, envelope detection) and ML-based anomaly classification using the ISM330DHCX's finite state machine and machine learning core, while the IIS3DWB delivers ultra-wideband acceleration data up to 6 kHz with low noise floor (75 µg/√Hz).

Power architecture integrates STBC02 linear battery charger (LiPo input, USB 5 V support) and ST1PS02 digitally programmable step-down converter (2.6–3.3 V output, 400 mA), enabling multi-source operation (LiPo, USB, primary battery) with precise voltage selection via D0/D1/D2 pins and power-good signaling.

FAQ

Does STEVAL-PROTEUS1 support over-the-air firmware updates?

Yes. The board supports secure OTA updates via Bluetooth LE using the STSAFE-A110 secure element for cryptographic signature verification and firmware image decryption. Preloaded firmware includes ST's FP-AI-PDMWBSOC function pack, which implements authenticated update workflows compliant with industrial security requirements.

What software tools are included with STEVAL-PROTEUS1?

The kit ships with STSW-PROTEUS software package, STM32Cube function pack FP-AI-PDMWBSOC, and STBLESensor mobile app (Android/iOS). These provide GUI-based sensor configuration, real-time FFT visualization, MLC model training tools, and prebuilt anomaly detection demos - all integrated with STM32CubeIDE and X-CUBE-AI.

Can STEVAL-PROTEUS1 operate without USB connection after initial setup?

Yes. It operates autonomously on its included 3.7 V, 480 mAh LiPo battery, with STBC02 enabling recharge via USB or external 5 V source. Power management includes ST1PS02 step-down converter (programmable 2.6–3.3 V) and ultra-low-power sleep modes (<1.5 µA RTC + backup RAM), supporting multi-week field deployment.

Is the STMOD+ expansion connector compatible with other ST evaluation boards?

Yes. The 34-pin STMOD+ connector follows ST's standardized mechanical and electrical specification (defined in AN5055), ensuring interoperability with other STMOD+-compatible boards like X-NUCLEO-IDW01M1, X-NUCLEO-IKS02A2, and X-NUCLEO-IKA01A1 - enabling modular sensor fusion and connectivity extension.
