The X-NUCLEO-NFC01A1 is a Dynamic NFC tag evaluation board to allow expansion of the STM32 Nucleo boards.
It is compatible with the Arduino UNO R3 connector layout and it is designed around the M24SR64-Y. The M24SR64-Y device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a 64 Kbit EEPROM memory. It can be operated from an I2C interface or by a 13.56 MHz RFID reader or a NFC phone.
The board is powered through the Arduino UNO R3 connectors. It also includes three LEDs for general purpose.
