Introduction

PN532 is a highly integrated non-contact read-write chip, which contains the 80C51 microcontroller core (this 8051 user cannot program it, it is a low-level communication protocol stack for built-in NFC), which integrates each of the 13.56MHz An active / passive contactless communication method and protocol.

The PN532 transmission module supports 6 different working modes:

  • Reader mode, support ISO / IEC 14443A / MIFARE? Mechanism
  • Reader mode, supports FeliCa mechanism
  • Reader mode, support ISO / IEC 14443B mechanism
  • Card operation mode, support ISO 14443A / MIFARE? Mechanism
  • Card operation mode, FeliCa mechanism
  • ISO / IEC18092, ECM340 point-to-point

This is a NFC motherboard based on 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 allows 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 system, smart tickets, meal card, etc.

Based on the popular NFC controller PN532 with multi interface options, this motherboard will easily enable NFC function for your Raspberry Python/C, STM32, Arduino.
