PN532 NFC RFID Module V5

PN532 NFC RFID Module V5

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, we can guaranteethe the performance stability of PN532 NFC RFID Module V5 !

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.

PN532 NFC RFID Module V5 is the newest updated version from PN532 NFC RFID Module V3.

Note: PN532 NFC RFID Module V5 is completely compatible with V3 on hardware and software. V5 also keeps exactly the same shape, installing holes and interface as V3.

Improved PCBA design、optimization of parameters and circuit, and wider bandwidth of antenna,  all of these optimized factors make PN532 NFC RFID Module V5 perform much better than V3.

Dimension

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.

Connection with Arduino

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 supply library for Arduino. 

2) P2P communication

The P2P NFC communication between two PN532 modules is only supported by I2C mode.

Note, while testing this library, please remove the libraries in the testing above (or other PN532 libraries) to other folders. Otherwise they might conflict.

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. 

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.
