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. We can set up two different output frame formats as needed. In addition, it integrates LGT8FF8A chip, compatible with Arduino library, thus we can modify the firmware for development and use to suit our own needs.

According to V1.0 firmware, there are two types of data output:
When a resistor (default) is soldered onto silkscreen "1" position on the board, the serial port will output a 10-digit decimal ACSII code card N.O. directly.
For example: the card number is 46553491, the output data will be "0046553491", (HEX: "0x30 0x30 0x34 0x36 0x35 0x35 0x33 0x34 0x39 0x31".
When a resistor (default) is soldered onto silkscreen "2" position on the board, the serial port will output a hexadecimal ACSII code with odd-even check as card N.O.
Format: Start frame(0x02)+ ID(10 byte)+ odd parity bit(1 byte)+ even parity bit(1 byte)+end frame (0x03)
For example: the card number is 46553491, the hexadecimal format of which shows as 0x02C65993, and the output data will be(HEX)“0x02 0x30 0x30 0x30 0x32 0x43 0x36 0x35 0x39 0x39 0x33 0x3E 0x4F 0x03”.
According to V1.0 firmware, once an ID N.O. is read, LED pin will output a 10ms high-level pulse.
