PN532 NFC HAT for Raspberry Pi

This Waveshare NFC HAT carries the PN532 chip and reads and writes NFC and RFID cards at 13.56 MHz. It fits the 40-pin header of the Raspberry Pi and can be addressed via I2C, SPI or UART. Via the side pin header it can also be connected to Arduino, ESP32, ESP8266 or STM32.

Recommended Accessories:

• NFC TAG Sticker Ntag213 13.56 MHz
• NFC TAG Stickers Ntag215 13.56 MHz
• RFID Tag Card Credit Card 13.56MHz RC522/ M1 S50

Features:

• Select the interface with jumpers I0 and I1: UART with I0 L and I1 L, I2C with I0 H and I1 L, SPI with I0 L and I1 H
• DIP switch connects the PN532 to the Raspberry Pi, only one interface at a time
• Jumper INT0 to D16 and RSTPDN to D20 of the Raspberry Pi
• Antenna on the board, power indicator PWR
• On the Raspberry Pi: I2C without clock stretching, with other I2C devices choose SPI or UART; SPI uses D4 as chip select
• Only reads and writes cards with a known or default password; encrypted cards cannot be read
• Reads and writes MIFARE and NTAG2xx cards
• Example code for Raspberry Pi, Arduino and STM32

Application Examples:

• Access control and door locking system
• Reading and writing NFC tags
• NFC applications with Android phones
