AJMRTC ST25DV16K I2C RFID Dynamic Tag RF Module, STEMMA QT Qwiic NFC Dynamic Tag Board, 16Kbit Memory Contactless RF Sensor for Arduino Raspberry Pi Microcontroller Projects

AJMRTC ST25DV16K I2C RFID dynamic tag RF module is built around the ST25DV16K dualinterface NFCRFID chip equipped with 16Kbit EEPROM storage. Distinct from static NFC tags, this unit enables connected microcontrollers to dynamically rewrite tag content over the I2C interface while supporting standard ISO 15693 contactless RF communication. Prefitted with STEMMA QT / Qwiic compatible port, the module supports quick interconnection with other Qwiic peripherals, removing soldering steps and shortening development cycles. Operating within 1.8V3.3V voltage range, it matches the logic level of most singleboard computers and microcontrollers. The compact PCB design facilitates hardware integration. It is widely applied in asset management, smart access control, interactive exhibition hardware, IoT trigger devices, maker experiments and embedded projects to realize flexible dynamic NFCRFID functions.
