STMicroelectronics Smart, flexible NFC Tracker Evaluation Board includes a comprehensive software library

STMicroelectronics Smart and flexible NFC tracker evaluation boards STEVAL-SMARTAG2 and STEVAL-SMARTAG1 are equipped with sensors. They include a comprehensive software library and a sample application for monitoring and logging sensor data via NFC from an Android or iOS device.

The ultra low Power Sensor Node evaluation board is mounted with a ST25DV NFC tag, a STM32L4 or STM32L0 Arm Cortex-M0+, environmental sensors (temperature, humidity, and pressure), and motion (accelerometer) sensors. The STEVAL-SMARTAG2 evaluation board can be equipped with a battery charger powered by a full wave rectifier for NFC energy collection. STEVAL-SMARTAG1 has NFC collection function for power supply and battery holder for CR2032 battery.
