STEMMA QT ST25DV16K I2C RFID EEPROM - module with RFID tag

Description

Module with an RFID tag based on the ST25DV16K chip. It supports the ISO/IEC 15693 (13.56 MHz) standard and can be used with Android and iOS mobile devices. The user can reprogram the tag using the I2C bus, so that the module can even be used as an I2C-RFID converter. It is compatible with 3.3 V and 5 V controllers, and communication is via the STEMMA QT connector. There is a PCB antenna on the board. Full documentation is available on the product page.
