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.

Data formats
According to V1.0 firmware, there is one type of data output:
- Directly output a card N.O.
The serial port will output a 10-digit decimal ACSII code card N.O. directly, which will be followed by a break line "0x0D 0x0A".
For example: the card number is 46553491, the output data will be "0046553491", (HEX: “0x30 0x30 0x34 0x36 0x35 0x35 0x33 0x34 0x39 0x31 0x0D 0x0A”).
Interrupt pin
- LED
According to V1.0 firmware, once an ID N.O. is read, LED pin will output a 10ms high-level pulse.
