13.56 MHz PN532 NFC Module for Arduino Suitable for reading and writing NFC cards on a raspberry pi

NFC RFID Module PN532

Unlike most RFID modules that are hardwired for SPI communication, the PN532 is an NFC RFID module clocked at 13.56MHz that offers the flexibility to switch between I2C, SPI, and TTL Serial communication modes using an onboard switch. It also features an integrated logic level shifter, enabling compatibility with both 3.3V and 5V power supplies.

Key Features:

• Supports I2C, SPI, and HSU (High-Speed UART) communication modes
• Functionable in both NFC mode and RFID reader/writer mode
• Integrated 3.3V voltage regulator provides 3.3V or 5V working voltage options
• Maximum communication distance of 3 cm
• Equipped with two 3mm mounting holes for easy integration into various projects, thanks to its compact size

Additional Notes:

• The module generates heat during normal operation.
• Recommended operating temperature range: -20°C to 85°C
• Recommended storage temperature range: -40°C to 125°C

Applications:

• Smart card applications
• Access control systems
• Inventory tracking
• Data collection
• Tagging and identification

With its versatility and ease of use, the PN532 NFC RFID Module is an ideal choice for a wide range of applications.
