Product details
Overview
STEVAL-SMARTAG2 from STMicroelectronics is an NFC-enabled sensor node evaluation board integrating an STM32L4P5 MCU, ST25DV64KC dynamic NFC/RFID tag IC (64-Kbit EEPROM, fast transfer mode), LSM6DSO32X 6-DoF inertial module (32 g accelerometer, embedded ML core), LIS2DUXS12 smart accelerometer (Qvar, ML core), LPS22DF pressure sensor (260–1260 hPa), VD6283TX multispectral ambient light sensor with flicker engine, and STSAFE-A110 secure authentication IC. It supports battery-powered (CR2032/LIR2032) or NFC energy-harvested operation for field-deployable asset tracking.
For engineers reviewing the STEVAL-SMARTAG2 datasheet, STEVAL-SMARTAG2 pinout, STEVAL-SMARTAG2 application, or STEVAL-SMARTAG2 equivalent, this page delivers verified hardware architecture, sensor fusion capabilities, NFC data exchange protocols, power management topology, and cloud-integrated proof-of-concept support via DSH-ASSETRACKING dashboard and STAssetTracking mobile app.
Technical Context
The board implements a dual-interface sensing architecture: NFC communication (ISO 15693, I²C slave interface to MCU) enables contactless configuration and data readout without external power, while the STM32L4P5 MCU executes local sensor fusion, event-triggered logging, and secure data signing via STSAFE-A110. All environmental and inertial sensors connect via dedicated I²C buses (I2C1/I2C2/I2C3) with configurable pull-ups and interrupt routing.
Sensor processing leverages on-device machine learning cores in LSM6DSO32X and LIS2DUXS12 for real-time activity classification and anomaly detection; the VD6283TX performs spectral analysis and light flicker measurement using hybrid optical filters; the LPS22DF and STTS22H provide calibrated barometric and temperature readings for environmental compensation and cold-chain monitoring.

FAQ
Does STEVAL-SMARTAG2 support NFC energy harvesting without a battery?
Yes - the ST25DV64KC dynamic NFC tag IC integrates an energy harvester that powers the board's sensors and MCU during NFC reader interrogation. The STLQ020 LDO regulates harvested voltage to 1.9 V, enabling full sensor operation and data logging without CR2032/LIR2032 battery. Energy-harvested mode supports periodic wake-up and short-duration measurements only.
How is sensor data transferred to cloud platforms?
Data is transmitted via the STAssetTracking mobile app (iOS/Android), which reads NFC-stored logs or connects over BLE (via optional firmware update). The app forwards encrypted payloads to the DSH-ASSETRACKING Amazon Web Services-based dashboard, supporting time-series visualization, geolocation tagging, and threshold-based alerting for temperature, pressure, impact, and light exposure events.
What firmware and software tools are provided?
ST provides STM32Cube function pack FP-SNS-SMARTAG2, including HAL drivers, sensor middleware, NFC tag memory mapping utilities, STSAFE-A110 secure services API, and sample applications for sensor fusion, event logging, and OTA updates. Full source code, Keil/IAR/STM32CubeIDE project files, and Android/iOS SDKs are included in the package.
Can the board operate in shelf-mode for long-term storage monitoring?
Yes - STSAFE-A110 supports shelf-mode activation, reducing system power to <1 µA by disabling non-essential peripherals while retaining RTC alarm capability and tamper-detection readiness. Shelf-mode is triggered via NFC command or GPIO, and exit is enabled through STSAFE's authenticated wake-up protocol to prevent unauthorized access.
