The PN532 is a highly integrated transmission module for contactless communication at 13.56 MHz including microcontroller functionality based on an 80C51 core with 40 Kbytes of ROM and 1 Kbytes of RAM. The PN532 combines a modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz with an easy-to-use firmware for the different supported modes and the required host controller interfaces.

It works as RFID reader/writer,1443-A card or a virtual card and also supports NFC with Android phone. It is also compatible with Arduino.


Pinout Diagram Details

Pins Details
VCC VCC is to power up the whole device.
GND  GND pin helps to make the common ground with power supply and the Arduino/Microcontroller.
UART Communication Pins
TXD UART communication requires two communication pins one for transmitting data and second for receiving it. TXD helps to transmit the data.
RXD The RXD pin is the data receiving pin of the UART communication.
I2C Communication Pins
SDA I2C communication requires one pin for data transmission and receiving. Therefore, in the PN532 module SDA is a data pin for I2C communication.
SCL SCL is the clock pin of I2C communication. Data travel between devices according to the clock pulse.
IRQ IRQ pin is an interrupt pin, which helps to I2C communication to generate the interrupt to get the attention of the Arduino/Microcontroller.
RST RST is a reset pin, which helps to reset the device through an external signal. In PN532 this device is for I2C communication.
SPI Communication Pins
MOSI SPI communication requires 4-pins for data communication. Therefore, MOSI is a Master Out Slave In pin, it helps to transmit data from Arduino to PN532.
MISO MISO is a Master In Slave Out, it helps to transmit data from PN532 to Arduino.
SS SS is a slave select pin; it activates the SPI communication of the Slave (PN532).
SCK It’s a clock pin, helps in Transreceiving of data according to the clock pulse.

How to use PN532 NFC Module?

For using PN532 module, first we will choose the mode of communication between MODULE and CONTROLLER. As mentioned earlier, this module has three interfaces, of which we have to choose one. Remember at any given point of time only one of three interfaces can be used. All three cannot be used together. We will have to choose the mode of interface using two switches solder to the board. The switches are S1 and S2 shown in pin diagram.

S1 S2 Interface
OFF OFF HSU (High Speed UART)
ON OFF I2C
ON ON SPI

Choose the mode of interface and corresponding state of switches from above table. Next toggle the switches S1 and S2 to those positions.

After choosing the type of interface, connect the module to the controller or processor. Say if you opted to use I2C, then connect module to I2C of the controller. If you opted to use SPI, then connect module to SPI of controller.

After interfacing you have to download the library files for the module from corresponding websites. Say for ARDUINO platform [https://www.arduinolibraries.info/libraries/adafruit-pn532]. Save the library files in the IDE program files.

Now all that left is to write the program for the controller or ARDUINO in the IDE software. And do call up on the saved library files while writing the program. With those libraries we can directly communicate with the module while skipping all the steps of communication protocol.

Once the programming is done, power up the circuit to get the desired response.

Where to use PN532 NFC Module?

  • PN532 module basically used to setup a communication mode to devices for quick data exchange.
  • PN532 module can be used on experimental products to communicate with smart phones and PC.
  • The module is used as a communication shield for ARDUINO and PI platforms.
  • The module can be used an RFID (Radio Frequency Identification) reader and writer.
  • The module itself can be used as RFID card.
  • The module consumes very less power so it can be used in mobile systems which work on battery.
  • The module can be used on any controller (or processer) who has any one of three Interfaces (I2C, UART, and SPI).
