Raspberry Pi PN532 NFC module, as its name implies, is based on PN532 chip and used to 13.56 MHz near field communication.
This module is equipped with on-board antenna, so there is no external antenna coil.
It is compatible with SPI, IIC interfaces to communicate. With the support of NFC library, Raspberry Pi can connect products with the function of NFC, thus it is easy to use.
13.56MHz NFC / RFID Shield Module PN532 for Arduino
Supports SPI / IIC / UART Interface
The NFC / RFID breakout base on PN532, which is the most popular NFC chip, and is what is embedded in pretty much every phone or device that supports NFC
This module 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 an NFC tag
If you want to do any sort of embedded NFC work, this is the chip you will want to use. The PN532 is also very flexible, you can use 5V 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 use it with any Linux / Mac / Windows computer
Comes with: the PN532 breakout board including a tuned 13.56MHz stripline antenna, 0.1 inch header, 2 jumpers / shunts and a 4050 level shifter chip
You can use SWITCH-0 and SWITCH-1 to choose UART, IIC or SPI interfacing
Dimensions: 3.1″ x 1.9″ x 0.47″ ( 79mm x 48mm x 12mm )
