This is a Raspberry Pi NFC HAT based on PN532 operating in the 13.56MH z frequency range. NFC (Near Field Communication) is a wireless technology that 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 systems, smart tickets, meal cards, etc.
It supports three communication interfaces: I2C, SPI, and UART, configured via jumpers and switches
Onboard standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
Reserving breakout control pins, for easily connecting with host boards like STM32/ and forArduino
Onboard PN532 chip, supports various NFC/RFID cards like MIFARE/NTAG2xx, etc. Based on the popular NFC controller PN532 with multi-interface options, this HAT will easily enable NFC function for your Raspberry Pi.
