Product Description
PN532 NFC HAT for Raspberry Pi, I2C / SPI / UART
Overview
- This is a Raspberry Pi NFC HAT 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 HAT will easily enable NFC function for your Raspberry Pi.
Features
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- Onboard PN532 chip, supports various NFC/RFID cards like 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)
