X-NUCLEO-NFC01A1 expansion board
The X-NUCLEO-NFC01A1 is an expansion board based on the M24SR64-Y device. This
expansion board can be plugged on the Arduino UNO R3 connectors of any STM32 Nucleo
board.
The M24SR64-Y device is a dynamic NFC/RFID tag IC with a dual interface. It embeds 64
Kbit EEPROM memory, and can be operated from:
an I²C interface
a 13.56 MHz RFID reader or a NFC phone.
The I²C interface uses a two-wire serial interface, consisting of a bidirectional data line and
a clock line. It behaves as a slave with respect to the I²C protocol.
The RF protocol is compatible with:
ISO/IEC 14443 Type A
NFC Forum Type 4 Tag.
The board is powered through the Arduino UNO R3 connectors and includes three general
purpose LEDs.
