The STMicroelectronics's dynamic NFC or RFID tag IC expansion board is based on the ST25DV64KC dynamic NFC or RFID tag IC with a 64-Kbit dual interface EEPROM and fast transfer mode feature. It can be powered through the STM32 Nucleo development board or directly through the received carrier electromagnetic field. It is compatible with the Arduino UNO R3 connector pin assignment and can easily be plugged onto any STM32 Nucleo development board. You can stack other expansion boards to evaluate different devices that work together with the dynamic NFC tag. The board also features a single-layer antenna with a diameter of 54 mm and copper etched on the PCB.
