Arduino Compatible RFID Pinouts | Adafruit ST25DV16K I2C | Adafruit RFID EEPROM Breakout 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). Adafruit ST25DV16K I2C RFID EEPROM Breakout - STEMMA QT / Qwiic (AF-4701 ST has written a handy library that you can easily use to write NFC URLs to the chip over I2C. This RFID tag is really unique: it works with mobile phones just like other RFID tags, but you can reprogram it over I2C We used both Apple and Android phones with success to read the tags. TDK InvenSense ICM-20948 9-DoF IMU (MPU-9250 Upgrade) [STEMMA Please use a Metro M0 or other SAMD chip (or better) to communicate with the ST25DV.
