Getting started with the X-NUCLEO-NFC04A1 NFC/RFID tag IC
expansion board based on ST25DV04K for STM32 Nucleo
Introduction
The X-NUCLEO-NFC04A1 dynamic NFC/RFID tag IC expansion board is based on the ST25DV04K
NFC Type V/RFID tag IC with a dual interface 4 Kbits EEPROM that also features an I²C interface. It
can be powered by the pin of Arduino connector or directly by the received carrier electromagnetic field.
The X-NUCLEO-
NFC04A1 expansion board is compatible with the Arduino™ UNO R3 connector pin
assignment and can easily be plugged onto any STM32 Nucleo board. Various expansion boards can
also be stacked to evaluate different devices operating together with the dynamic NFC tag.
The board also features an antenna with a 54 mm iso 24.2 diameter, single layer, copper etched on
PCB.
