Raspberry Pi PN532 NFC HAT

Product Description

• The Raspberry Pi NFC HAT is a module based on the PN532 that operates in the 13.56MHz frequency range.
• It supports I2C, SPI, and UART interfaces.
• NFC (Near Field Communication) is a wireless technology that allows contactless point-to-point data communication between devices within a short distance, typically around 10 cm.
• It is widely used in applications such as access control systems, smart tickets, meal cards, and more.
• This HAT, based on the popular NFC controller PN532 with multiple interface options, will easily enable NFC functionality for your Raspberry Pi.
