How to use of RDM6300 125KHz RFID Reader Module with Built-In Antenna
Interface Function
-
UART Output (TX Pin): Outputs data in UART mode as 10 ASCII codes + 1 space. The card number format is 10 data. Baud rate is 9600.
-
IO Direct Output (J2 Pin): Indicates successful card swiping with high level during data output, and low level when idle.
-
Triode Open Drain Output (J1 and J2 Pins): Open drain output for subsequent upgrades such as driving relays. The fill current should not exceed 100mA.
Connecting the Module
-
Connect VCC to a 3.3-5V power supply.
-
Connect GND to ground.
-
Use TX for UART data output.
-
Use J2 for direct IO output indication.
-
J1 for open drain output, if needed for driving external loads.
