Description

Amazon Note that the most popular hobby RFID reader/writer chips like the PN532 do not support ISO15693 so you cannot use those to read the ST25DV tag once programmed! We used both Apple and Android phones with success to read the tags. According to the datasheet, one can even use it as an 'I2C to RFID' transfer system to wirelessly send and receive data from mobile devices (you'll need to write a custom app for that kind of project, though). ST has written a handy library that you can easily use to write NFC URLs to the chip over I2C. You cannot use an Arduino UNO (ATmega328p) with the ST25DV library, there's not enough RAM. Please use a Metro M0 or other SAMD chip (or better) to communicate with the ST25DV. There's no Python or CircuitPython library for this chip at this time, only Arduino.
