RDM6300 RFID Reader Module – 125KHZ

RDM6300 RFID Reader Module – 125KHz Serial Interface for Contactless Identification

Detailed Description:
The RDM6300 RFID Reader Module is a compact and efficient 125KHz RFID reader designed for contactless identification and access control applications. It reads EM4100 compatible RFID cards or tags and outputs data via a simple UART (serial) interface, making it perfect for integration with microcontrollers like Arduino, ESP32, or Raspberry Pi.

Operating at 125KHz, this module is ideal for low-frequency RFID applications where cost, simplicity, and stability are key. It supports a reading distance of up to 5–10 cm depending on tag size and operates with minimal power—perfect for embedded and portable systems.
