Description

Adafruit has taken their popular PN532 breakout board and turned it into a shield – the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC. This chipset is very powerful, and 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. While the controller has many capabilities, our Arduino library currently only supports reading/writing tags, and does not support phone-to-shield communication, tag emulation (which requires an external ‘secure element’ only available from NXP) or other more advanced features at this time.

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. It can also work with any other NFC/RFID Type 1 thru 4 tag.

The Adafruit shield was designed by RF engineers using the best test equipment to create a layout and antenna with 10cm (4 inch) range, the maximum range possible using the 13.56MHz technology. You can easily attach the shield behind a plastic plate with standoffs and still read cards through a (non-metal) barrier.

This shield is designed to use I2C or SPI communication protocols. I2C is the default, as it uses fewer pins: analog 4 and 5 are used for I2C (of course you can still connect other I2C devices to the bus). Digital #2 is used for “interrupt” notification. This means you don’t have to sit there and ‘poll’ the chip to ask if a target tag has been found, the pin will pull low when a card, phone, etc is within range. You can adjust which pin is used if you need to keep digital #2 for something else.

This shield is compatible with any classic Arduino (NG, Diecimilla, Duemilanove, UNO) as well as the Mega Rev3. If using an older Mega two wires must be run from the shield to the I2C pins. The shield also works with Arduino compatible boards including the Adafruit Metro and SparkFun Redboard.

Each kit includes the RFID shield, 36pin header, and a Mifare Classic 1k Card.

    Hi,

    What are the minimum and maximum temperatures of this board? Can it go outside at -45C ?

    Thank you!

      Hello, All components on the board are rated from -30° to 85°C but the assembled unit has not been tested.
