Near Field Communication (NFC) is a popular technology in the recent years with many smartphones are adopting it.
PN532 NFC Breakout Board enables you to add Near Field Communication in your electronics or embedded prototyping project. The PN532 chip from NXP is widely used in many NFC enabled devices and able to read/write NFC tags as well as performs peer-to-peer communication with other NFC devices. It can also perform "tag emulation" where it act like a NFC tag. This chip is also popular among open-source communities and there are already quite a number of libraries supporting it.
You can use I2C, SPI or HSU (High Speed UART) to talk to this board. The communication mode can be selected by a DIP switch on-board.
A built-in antenna, tuned to 13.6MHz is surrounding the board edges. The communication range is around 5 to 7 cm.
This board is not fully assembled, some light soldering is required.
Features:
Small dimension: 42.7 mm x 40.4 mm
Reading distance: ~ 5-7 cm
On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI
Communication protocol:
I2C/HSU: 3.3V-5V, share the same pins. Pins definition for I2C is printed at the front, HSU at the back
SPI: 3.3V TTL with 100 ohm resistors in series - can be connected directlyto 5V system such as Arduino
Built-in antenna
Read and write multiple protocol tags including Mifare, FeliCa and NFC Forum Tag Type 1 to 4
Host communication via HSU (High Speed UART), I2C or SPI interface, changeable by a DIP switch. The default is HSU
