Raspberry Pi NFC HAT based on PN532 with 13.56 MHz frequency range and interfaces I2C SPI UART for payment system and Bluetooth and WiFi devices chaining and smartphone NFC Fafeicy Over 32 GPIO pins areThis is a Raspberry Pi NFC HAT based on PN532 that operates in the 13. 56 MHz frequency range. It supports three communication interfaces: I2C, SPI and UART. 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 system, smart tickets, food card, etc. Based on the popular NFC controller
