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.
       
  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 PN532. 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 532 on this module. Users could    easily connect and play.  On this module, I2C is the data Interface by    default. With our Arduino Sensor Shield,   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 and Small dimension and easy to embed into your project
       
        2、Support I2C、SPI and HSU (High Speed UART), Change between those modes
       
        3、Support RFID reading and writing
SupportP2P communication with peers
Support NFC with Android phone

4、Typical Operating Distance have been updated to 5cm~7cm reading distance

5、Work in NFC Mode or RFID reader/writer Mode

6、RFID reader/writer supports:

1) Mifare 1k, 4k, Ultralight, and DesFire cards

2) ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX)

3) Innovision Jewel cards such as IRT5001 card

4) FeliCa cards such as RCS_860 and RCS_854

7、Plug and play, Arduino compatible

8、Built in PCB Antenna, with 4cm~6cm communication distance

9、On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI

10、Work as RFID reader/writer

11、Work as 1443-A card or a virtual card

12、Exchange data with other NFC devices such as smartphone

Interface :

The   version 3 can support I2C、SPI and HSU (High Speed UART), there is a   switch can help you to change interface between those modes easily.
   

Hardware Connection :
       
        If you have Sensor Shield, you could plug in and play.
       
       
     

        And you can finish connection with Arduino by hand :
       
        Arduino GND to PN532 Module GND
       
        Arduino 5V to PN532 Module VCC
       
        Arduino SDA to PN532 Module SDA
       
        Arduino SCL to PN532 Module SCL
       
        Dimension :
     

       
          Application :
       
        Here we introduce 3 basic example of this module.
       
        1) Read/write RFID card
       
        As basic function, this module could read and write RFID card. Various cards could be supported.
       
        We also supply libraries for Arduino.
       
     

        2) P2P communication
       
     

        Two PN532 modules could communicate with each other wirelessly.
       
        3) NFC with Andriod Phone
     

        The   basic communication stamp with Andriod Phone (NFC supported) is   finished. Currently we could put an URL to Android phone and let it   visit a webpage.
