Getting started with X-NUCLEO-NFC03A1 NFC card reader

board

based on CR95HF IC for STM32 Nucleo

Introduction

The X-NUCLEO-NFC03A1 is an NFC card reader evaluation board based on CR95HF integrated circuit

to allow expansion of the STM32 Nucleo boards. The CR95HF is card reader IC for contact-less

application that provides the 13.56MHz air interface, frame coding and decoding for standard

application such as Near Field Communication (NFC) and that communicates with the Host through

UART or SPI interface. X-NUCLEO-NFC03A1 is compatible with the Arduino UNO R3

connector

assignment.

This expansion board can be plugged into the Arduino UNO R3 connectors of any STM32 Nucleo

board. The different expansion boards can

be easily stacked to allow evaluation of different devices

with NFC card reader.

The board has the following features:

•

On-board NFC card reader IC: CR95HF

•

47 x 34 mm, 4 turns, single layer 13.56 MHz inductive antenna etched on PCB and

associated tuning circuit.

•

4 general purpose LEDs

UM1799 Getting started

Getting started

This section describes the hardware requirements for the X-NUCLEO-NFC03A1

evaluation

board.

1.1 Hardware requirements

The X-NUCLEO-NFC03A1 is an expansion board for use with STM32 Nucleo boards. To

function correctly, the X-NUCLEO-IDB05A1 must be connected to the STM32 Nucleo

board as shown in Figure 2: "X-NUCLEO-NFC03A1 plugged into an STM32 Nucleo

board

through the Arduino UNO R3 connector" below.

The STM32 Nucleo firmware and related documentation is available at

http://www.st.com/stm32nucleo

Figure 2: X-NUCLEO-NFC03A1 plugged into an STM32 Nucleo board through the Arduino UNO

R3 connector

4/16 DocID026680 Rev 1

The interconnection between the STM32 Nucleo and the X-NUCLEO-NFC03A1 has been

designed to permit the use of any STM32 Nucleo board, although complete testing has

been performed using the

NUCLEO-F401RE hosting the dynamic efficiency STM32.

1.2 System requirements

Using the Nucleo boards with the X-NUCLEO-NFC03A1 expansion board requires

the

following software and hardware:

•

Windows PC (XP, Vista, 7, 8) to install the firmware package

•

USB type A to Mini-B USB cable to connect the Nucleo board to the PC

Installation of the board firmware package (order code: X-CUBE-NFC3) on the user's PC

requires the following:

•

128 MB of RAM

•

40 MB of hard disk space

The X-CUBE-NFC3 firmware and related documentation is available on www.st.com

1.3 Setting up the board

To set up the board, perform the following steps:

Connect the X-NUCLEO-NFC03A1 on the Nucleo board from the top as shown in

Figure 2: "X-NUCLEO-IDB05A1 plugged into an STM32 Nucleo board through the

Arduino UNO R3 connector"

Power the Nucleo board using the Mini-B USB cable delivered with the board.

Program the firmware in the STM32 on the Nucleo board using the provided firmware

example

Reset the MCU board using the reset button available on the Nucleo board

The evaluation kit is ready to be used

This section describes the X-NUCLEO-NFC3A1 features and provides information which

could be useful to understand the board schematic diagrams.

2.1 X-NUCLEO-NFC03A1 board

The board allows the user to test the functionality of the CR95HF integrated circuit. The

CR95HF supports reader/writer mode and supports following communication protocols:

ISO/IEC 14443 Type A and B, ISO/IEC 15693, ISO IEC18092, MIFARE ® Classic.

Its functionality can be exploited using the firmware package contained in the X-CUBE-

NFC3. It is fundamental to program the microcontroller on the STM32 Nucleo board. Please

refer to user manuals UM1724 and UM1725, available on www.st.com.

The

CR95HF integrated circuit

module and the STM32 Nucleo board are connected

through connectors

CN5, CN6, CN8 and CN9 (see Table 1: "Interconnection between

STM32 Nucleo board

and X-NUCLEO-NFC03A1 left-side connectors" for details).
