The reading distance is up to 5CM. Coil inductance is 47~68uH.

Direct serial output operation:

1. RDM6300 card reader module wiring is as follows: 5V power supply.

2. Upload an empty program to the Arduino development board:

void setup(){}

void loop(){}

3. Arduino IDE serial output data:

The RDM630 series is a specialized module for non-contact RF ID cards, using advanced RF receiving circuits and embedded microcontroller design, combined with efficient decoding algorithms to receive data from EM4100 compatible ID cards. It features high receiving sensitivity, low working current, and high stability, suitable for various RF identification application fields such as access control, attendance, payment, anti-theft, and patrol.

The reading distance is up to 5CM. Coil inductance is 47~68uH.

This RFID card reader module is commonly used by Arduino users abroad and can read 125K EM4100 series RFID cards. The module is easy to use; after powering it, connect it to the Arduino main board. When an RFID card enters the reading range, the module will directly send the card number to the Arduino via UART. Then, by connecting a relay module to the Arduino, simple access control can be achieved.
