Dynamic NFC tag expansion board based on M24LR for STM32 Nucleo

The X-NUCLEO-NFC02A1 is a dynamic NFC/RFID tag board based on M24LR04E-R, for expansion of STM32 Nucleo boards.

The M24LR04E-R is an NFC Type V/RFID tag IC with a dual-interface 4 Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) that also features an I2C interface.

The EEPROM is organized as 512 x 8 bit in the I2C mode and as 128 x 32 bit in RF mode. It can be operated either from an external power supply or directly powered by the received carrier electromagnetic field.

The tag provides an user configurable digital output pin toggling during either RF Write in Progress or RF Busy mode.

The M24LR04E-R provides an Energy Harvesting mode. When activated, the M24LR04E-R delivers the excess energy coming from the RF field on the Vout analog pin. In case the RF field strength is insufficient or when Energy Harvesting mode is disabled, the analog output pin Vout goes into high-Z state and Energy Harvesting mode is automatically stopped.

The X-NUCLEO-NFC02A1 is compatible with the Arduino™ UNO R3 connector pin assignment and interfaces with the STM32 MCU via the I2C pins.
