The PN532 NFC Module is a versatile, high-performance NFC reader/writer based on the NXP PN532 chip. Supporting I²C, SPI, and High-Speed UART (HSU), it operates at 3.3–5 V and reads/writes ISO/IEC 14443-compliant NFC tags (e.g., MIFARE) at a typical range of 5–7 cm. Ideal for access control, mobile payment, attendance systems, IoT-authentication, and microcontroller-based NFC projects with Arduino, Raspberry Pi, or ESP32. |
