Getting started with X-NUCLEO-NFC02A1 dynamic NFC/RFID tag
IC expansion board based on M24LR04E-R for STM32 Nucleo
Introduction
The X-NUCLEO-NFC02A1 is a dynamic NFC/RFID tag IC expansion board based on
M24LR04E-R to allow expansion of STM32 Nucleo boards.
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.
It can be operated either from an external power supply, or directly powered by the received
carrier electromagnetic field.
X-NUCLEO-NFC02A1 is compatible with the Arduino™ UNO R3 connector pin assignment
and can readily be plugged onto any STM32 Nucleo board. Various expansion boards can
be easily stacked to allow evaluation of different devices operating together with the
dynamic NFC TAG.
The board, shown in Figure 1, features:
• On-board M24LR04E-R NFC Type V/RFID tag IC
• Copper etched, double layer 30 mm * 30 mm PCB Antenna
• Selectable power supply: the board is either powered from the STM32 Nucleo Board or
self-powered
• Three general purpose LEDs

1 Getting started
This section describes the hardware requirements for the X-NUCLEO-NFC02A1 expansion
board for STM32 Nucleo.
1.1 Hardware requirements
The X-NUCLEO-NFC02A1 is an expansion board to be used with STM32 Nucleo boards.
To operate correctly, the X-NUCLEO-NFC02A1 must be connected to the STM32 Nucleo
board.
The STM32 Nucleo firmware and the related documentation are available on www.st.com.
The interconnection between the STM32 Nucleo and the X-NUCLEO-NFC02A1 is designed
so that any STM32 Nucleo board can be used. Complete testing has been performed on the
NUCLEO-L053R8 (based on the ultra-low power STM32L053R8), and the
NUCLEO-F401RE (hosting the dynamically efficient STM32F401RE).
1.2 System requirements
To use the STM32 Nucleo boards with the X-NUCLEO-NFC02A1 expansion board and to
install the board firmware package (order code: X-CUBE-NFC2) the user needs
• a PC with Keil®, IAR™ or Keil® AC6 Embedded Development Tool
• a USB type A to Mini-B USB cable to connect the STM32 Nucleo board to the PC
The X-CUBE-NFC2 firmware and the related documentation are available on www.st.com.
The microcontroller on the STM32 Nucleo board must be programmed. For further
information about usage of STM32 Nucleo board, refer to user manuals UM1724 and
UM1725, available on www.st.com.
1.3 Setting up the board
To set up the board, perform the following steps:
1. Check that the jumper on the ST1 connector X-NUCLEO-NFC02A1 is in place. This
jumper provides the required voltage to the device on the board
2. Connect the X-NUCLEO-NFC02A1 on the STM32 Nucleo board from the top
3. Power the STM32 Nucleo board using the Mini-B USB cable
4. Program the firmware in the STM32 on the Nucleo board using the provide example
5. Reset the MCU board using the reset button available on the STM32 Nucleo board
6. The kit is ready to be used

2 Hardware description
This section describes the X-NUCLEO-NFC02A1 features and provides useful information
to understand the board schematic diagrams.
2.1 X-NUCLEO-NFC02A1 board
The board allows the user to test the functionality of the M24LR04E-R device, a Dynamic
NFC/RFID tag IC with a dual-interface EEPROM. It features an I2C interface and can be
operated from a VCC power supply. It is also a contactless memory powered by the
received carrier electromagnetic wave.
The M24LR04E-R is organized as 512 × 8 bits in the I2C mode and as 128 × 32 bits in RF
mode. The M24LR04E-R also features an energy harvesting analog output, as well as a
user-configurable digital output pin toggling during either RF write in progress or RF busy
mode.
The M24LR04E-R provides an Energy Harvesting mode on the analog output pin Vout.
When the Energy Harvesting mode is activated, the M24LR04E-R can output 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 M24LR04E-R also features an user configurable open drain output pin toggling during
either during RF Write in Progress or RF Busy.
These functionalities can be exploited using the firmware package X-CUBE-NFC2.
Two versions of X-NUCLEO-NFC02A1 exist, a red one and a blue one. They have the same
functionality, the differences between them are the board color and the designation of
Arduino™ connectors. More in detail, the following equivalence applies:
• CN5 = CN1
• CN6 = CN2
• CN8 = CN3
• CN9 = CN4
The X-NUCLEO-NFC02A1 expansion board and the STM32 Nucleo board are connected
through connectors CN5, CN6, CN8 and CN9 (see
Table 1 and Ta bl e 2 for details).

2.2 Power Supply and GPIO options
2.2.1 Power Supply option
The X-NUCLEO-NFC02A1 board contains the M24LR04E chip. In addition to basic
functionalities (NFC & I2C) of this dynamic NFC/RFID tag IC, some jumpers on board permit
to configure extra features.
• ST1: selects the M24LR power source: external (Nucleo Board power supply) or
M24LR energy harvesting
• ST2: M24LR energy harvesting is used to power Nucleo STM32 board.
If this feature is used, user has to make sure that the Nucleo STM32 board can
accommodate this power configuration (SB2&SB12 removed).

Hardware description UM1800
2.2.2 GPIO options
The M24LR_WIP/BUSY optional signal can be disconnected from the Nucleo STM32 Board
by removing R1 resistor.
The same option applies to the lines driving the 3 general purpose LEDs (MCU_LED1,
MCU_LED2 and MCU_LED3), that can be dedicated to other purposes (by removing,
respectively, R2, R3 and R4).
Refer to the schematic diagrams for details.
In case these connections are modified the firmware must be updated to enable proper use
of the STM32 resources.
