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
