PN532 NFC RFID Module User Guide
Version 3
Introduction
NFC is a popular technology in recent years. We often heard this word while smart phone company such as Samsung or HTC
introduces their latest high-end phones. Almost all the high-end phones 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. 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. 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
connect those pins.

developing
Arduino UNO only has one serial interface which is also connected to USB port to PC. In HSU mode, the serial monitor could not be
used as message displaying windows.
Function Test
RFID Reader/Writer
Here we show how to read and write RFID card with this module.
Download the library PN532 at our github page. You could find 4 folders in the library. Unzip the 4 folders at the library folder in
Arduino IDE.
Start Arduino IDE and choose the example:

NFC with Android phone
Download the library of NFC_Module_DEV from our github page.
Note, while testing this library, please remove the libraries in the testing above (or other PN532 libraries) to other folders. Otherwise they might
conflict.
Currently this library only supports HSU mode. We are still working on more modes. If you want to use SPI mode, you could try NFC_Shield_DEV. Just
connect Arduino with our PN532 module through SPI interface in the way shown in the table above.
Open the example in Arduino Due:
