Introduction

NFC is a popular technology in recent years. We often heard this work while smartphone company such as Samsung or HTC introduces their latest high-end phones. Almost all the high-end phone in the market support NFC.

Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters.

For electronics geeks, we also want to use NFC technology to make our own things. So we build this NFC RFID module. This module is built around NXP PN532. NXP PN532 is very popular in NFC area. And the company offers much technology document to help developers. We developed this module based on the official document. And to make things easier, we also build library for this module.

We almost break out all the IO pins of NXP532 on this module. Users could easily connect and play. On this module, I2C is the data Interface by default. With our Arduino Sensor Shield V6, it is very easy to plug and play. However, if users want to use other interface such as UART or SPI, this module also makes it easy to break out those pins.

Feature

1. Gilt PCB
2. Work in NFC Mode or RFID reader/writer Mode
3. RFID reader/writer supports:
   • Mifare 1k, 4k, Ultralight, and DesFire cards
   • ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX)
   • Innovision Jewel cards such as IRT5001 card
   • FeliCa cards such as RCS_860 and RCS_854
4. Plug and play, Arduino compatible
5. Built in PCB Antenna, with 4cm~6cm communication distance
6. On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI
7. Work as RFID reader/writer
8. Work as 1443-A card or a virtual card
9. Exchange data with other NFC devices such as smartphone

Interface

I2C interface is set as default inteface. However, users could change the interface by

All the useful IO pin are broken out with defination aside.

Hardware connection

If you have Sensor Shield, you could plug in and play

Or you could wire by hand:

Arduino PN532 Module
GND <---------------------> GND
5V <---------------------> VCC
SDA <---------------------> SDA
SCL <---------------------> SCL

Code and library

Here we supply code and example to read and write RFID card. Please click here to download the library.

With NFC function, two of PN532 modules could communicate with each other.
