RDM8800 De ITEAD Wiki Contenido 1 Overview 2 Specifications 3 Electrical characteristics 4 Hardware 5 pinmap 6 Data formats 7 Interrupt pin 8 Download 9 Useful Links Overview RDM8800 card reader is a module based on PN532 chip customized for 13.56MHz NFC RFID card, compatible with RDM6300 interface, which can read data directly from the serial interface. Unlike ordinary RFID modules, RDM8800 integrates LGT8FF8A chip, compatible with Arduino library, thus we can modify the firmware to suit our own needs. Itead Studio also released the source codes of RDM8800 firmware, and users can make secondary development based on it. Specifications PCB size 38.1mm X 17.78mm X 1.6mm Input voltage 5V Interface UART Compatibility With ISO 14443 Type A protocol With ISO 14443 Type B[1] protocol Baud rate 9600 [1]: Version 1.0 firmware does not support ISO 14443 Type B at present, which requires users to make secondary development.
