PN532 NFC Module for Raspberry Pi
.
Introduction
The ITEAD PN532 NFC module, as its name suggests, is based on the PN532 chip for near field communication at 13.56 MHz. The module is equipped with an onboard antenna so there is no external antenna coil. It is compatible with SPI, IIC, and UART interfaces for communication. With the NFC library supporting Arduino and the Raspberry Pi we offer, the development of NFC-enabled products is very convenient.
.
Characteristics
- The longest effective communication distance is 5 cm
- Support SPI, IIC, UART interface switching.
- Can be used for 13.56M contactless communication
- Compatible with ISO14443 TYPE A and Class B standards
