Adafruit PN532 NFC/RFID controller breakout board (v1.6)

The Adafruit PN532 NFC/RFID Controller Breakout Board supports reading and writing 13.56MHz NFC/RFID tags, with I2C, SPI and UART connectivity, a built-in antenna and support for communication with compatible NFC devices.

The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and 'act' like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you'll want to use! NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range Bluetooth® that doesn't require authentication. It is an extension of RFID, so anything you can do with RFID you can do with NFC. You can do more stuff with NFC as well, such as communicate bi-directionally with cell phones Because it can read and write tags, you can always just use this for RFID-tag projects. We carry a few different tags that work great with this chip (please see our Awesome Extra section). It can also work with any other NFC/RFID Type 1 thru 4 tag. The PN532 is also very flexible, you can use 3.3V TTL UART at any baud rate, I2C or SPI to communicate with it. This chip is also strongly supported by libnfc, simply plug in an FTDI cable and use the FTDI serial port device to communicate - this lets you do NFC dev using any Linux/Mac/Windows computer! We also include onboard power LED, 3.3V regulator and an FTDI header so you can plug in an FTDI friend or FTDI cable and use with libnfc. Comes with: the PN532 breakout board including a tuned 13.56MHz strip line antenna, 0.1" header, 2 jumpers/shunts and a 4050 level shifter chip. We also toss in a 13.56MHz 1K card!

Revision History

* As of January 3, 2024 - We've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen.

* As of Oct 31, 2014 - we updated the PCB design to allow the PN532 to enter low-power mode. The code, pinout, shape, etc are otherwise the same!
