Product Overview:
Our PN532 NFC module is based on a common board design for the PN532 chip used in near field communication (NFC) applications in the 13.56MHz frequency range with a maximum communication distance of 30mm. The board possesses it's own antenna and is capable of communicating via SPI, IIC (I2C) and UART. The board is designed to be compatible with both type A and B ISO14443 standards. There are also libraries available for both Raspberry pi and Arduino.

Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
