Description

This is a Raspberry Pi NFC HAT based on the PN532 operating in the 13.56MHz frequency range. It supports three communication interfaces: I2C, SPI, and UART.

NFC (Near Field Communication) is a wireless technology allowing contactless point-to-point data communication between devices within a short distance of 10 cm. It is widely used in applications such as access control systems, smart tickets, meal cards etc.

Based on the popular NFC controller PN532 with multi-interface options, this HAT will easily enable NFC functions for your Raspberry Pi project.

The board comes bundled with a single MIFARE Classic 1K NFC Card.

Features

  • Standard Raspberry Pi 40-pin GPIO extension header
  • Onboard PN532 chip, supports various NFC/RFID cards such as MIFARE/NTAG2xx etc.
  • Three interface options: I2C, SPI, and UART, configured via jumpers and switches
  • Breakout control pins for easily connecting with host boards like STM32/Arduino
  • Comes with development resources and manual (examples for Raspberry Python/C, STM32, Arduino)
