PN532 NFC RFID Module V3

Description
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 guarantee that all of our PN5321A3HN/C106 is 100% original from NXP, so we can guaranteethe the performance stability of this PN532 NFC RFID Module V3 !
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 the 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 5cm~7cm communication distance
9、On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL for SPI
10、Work as RFID reader/writer
11、Work as 14443-A card or a virtual card
12、Exchange data with other NFC devices such as smartphone
13、42.7mm*40.4mm*4mm

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.
The I2C and HSU shares the same pins. The definition of IIC pins is printed at front and the HSU’s is printed at the back. The HSU mode is configured as the default mode. But you could change the interface by setting the toggle switch.

| Working Interface | Channel 1 | Channel 2 |
| HSU | OFF | OFF |
| I2C | ON | OFF |
| SPI | OFF | ON |
Connection with Arduino

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 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.
