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 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 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) 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.
