PN532 NFC RFID Read Write Module V3 Kit

Description of PN532 NFC RFID Read Write Module V3 Kit The PN532 is a highly integrated transmission module for contactless communication at 13.56 MHz including microcontroller functionality based on an 80C51 core with 40 Kbytes of ROM and 1 Kbytes of RAM. The PN532 combines a modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz with an easy-to-use firmware for the different supported modes and the required host controller interfaces.It works as RFID reader/writer,1443-A card or a virtual card and also supports NFC with Android phone. It is also compatible with Arduino. Features: Support II2, SPI and HSU (High-Speed UART) I2C / UART: 3.3V ~ 24V TTL SPI: 3.3V TTL with 100-ohm resistors in series Communication distance: 5cm~7cm On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI Work in NFC Mode or RFID reader/writer Mode RFID reader/writer supports: Plug and play, compatible Built-in PCB Antenna, with 4cm~6cm communication distance On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI Work as an RFID reader/writer Work as a 1443-A card or a virtual card Exchange data with other NFC devices such as a smartphone.
