SparkFun Qwiic Dynamic RFID Tag - ST25DV64KC (SPX-19035)

An Arduino library for the ST25DV64KC Dynamic NFC/RFID Tag.

With this library, you can:

  • Write WiFi credentials to the tag using your smart phone and then have your Arduino board read them via I2C
  • Log data from your Arduino project into the tag's EEPROM memory and then read it back with your smart phone - even while your Arduino board is asleep or powered off!
  • Configure or update your project's keys, usernames or passwords securely and easily using contactless near field communication

Key Features

  • Provides a comprehensive set of methods to:
    • Read and write the tag's user memory
    • Adjust the size of the four memory areas
    • Change the I2C and RF passwords and read/write protection
    • Enable RF detection and Energy Harvesting
  • Includes enhanced methods to:
    • Write the tag's Capability Container (CC) File
    • Read and write multiple NDEF URI records
    • Read and write multiple NDEF WiFi records
    • Read and write multiple NDEF Text records
