Description

The STEVAL-SMARTAG2 is an NFC-enabled sensor node with inertial MEMS

sensors and environmental sensors, an STM32 microcontroller, and a dynamic NFC

tag for communication with NFC readers, such as tablets and smartphones.

Optionally, the STEVAL-SMARTAG2 can be equipped with: a battery charger fed by a

full-wave rectifier for NFC energy harvesting (on top of the energy harvester already

embedded in the dynamic NFC tag), a secure element to support authentication and

state-of-the-art crypto security, and a real-time clock (RTC) with an embedded crystal

oscillator to enable an accurate timekeeping and time stamping.

The board has a small and thin form factor, comparable to the size of a credit card,

which makes it particularly fit for deployment in the field and data collection.
