Grove NFC ST25DV64K- chip Versatile NFC/RFID tag board 3.3V/5V power supply

The Grove NFC ST25DV64K is a dynamic NFC/RFID tag board built around the ST25DV64K chip from STMicroelectronics. A phone or NFC reader can read and write its memory wirelessly, while your Arduino, ESP32 or Raspberry Pi reads and writes the same memory over I2C through the Grove connector. It runs from 3.3 V or 5 V, so it fits most maker boards.

• Access control, asset tracking and IoT learning projects

What's in the Box

• 1 × Grove NFC ST25DV64K tag board

Tip: Connect the board to an I2C Grove port, or to SDA, SCL, VCC and GND on your board, and use an ST25DV library in the Arduino IDE (STMicroelectronics publishes one). Keep metal away from the antenna area, as it shortens the reading distance.
