Wave NFC HAT for Pi, ISC, SPI & UART

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.

W16958-003

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.

Board Layout

PN532-NFC-HAT-intro

  1. Raspberry Pi GPIO connector: for connecting with Raspberry Pi
  2. PN532 control pins: for connecting with other host boards like STM32
  3. NFC induction coil
  4. PN532 chip: NFC controller
  5. Power indicator
  6. DIP switches: for configuring the connection between PN532 and Raspberry Pi (only one of the I2C/SPI/UART can be connected at the same time)
  7. Mode selection
  • I0-L, I1-L: enable UART
  • I0-H, I1-L: enable I2C
  • I0-L, I1-H: enable SPI
INT0 jumper: response signal, connects to Raspberry Pi D16 RSTPDN jumper: reset signal, connects to Raspberry Pi D20
