RFID Card Reader Module (RDM6300)

Overview

The RFID Card Reader Module (RDM6300) is a compact and reliable 125kHz RFID reader for reading proximity cards and tags. Designed for hobbyists and professionals, the RDM6300 offers easy integration with Arduino and other microcontrollers through a simple UART serial interface. Use it to add secure identification, access control, or asset tracking to your projects.

Key Features

• 125kHz RFID Technology: Reads standard low-frequency RFID cards and tags for proximity-based identification.
• UART Serial Communication: Simple TX/RX serial interface (TTL) for easy connection to Arduino, ESP boards, Raspberry Pi (via USB-serial), and other microcontrollers.
• Wide Voltage Compatibility: Operates from 3.3V to 5V, compatible with most development boards and systems.
• Read Range: Reliable reading distance up to 10 cm depending on card and environment.
• Compact Form Factor: Small size for embedding into enclosures, panels, or custom housings.
• Easy Setup: Minimal wiring and clear serial output make it fast to prototype and deploy.
• Reliable Performance: Stable operation with consistent card detection for access control and automation applications.

Technical Specifications

• Model: RDM6300
• Operating Frequency: 125 kHz
• Interface: UART (TTL serial)
• Supply Voltage: 3.3V to 5V
• Read Range: Up to 10 cm (varies with card/tag type)
• Output: Card UID and tag data over serial

Compatibility and Integration

The RDM6300 is ideal for Arduino, ESP8266/ESP32, STM32, and Raspberry Pi projects. Hook the module’s TX and RX pins to your microcontroller serial pins (use a common ground). Because it supports 3.3V to 5V power and TTL signaling, level shifting is typically not required when used with most development boards.

Typical Applications

• Access control and door entry systems
• Employee attendance and identification systems
• Asset tracking and inventory management
• Home automation and smart locks
• Security sensor and monitoring systems
• Educational and prototyping projects

Benefits for Your Projects

• Quickly add RFID identification to projects without complex hardware or software
• Reduces development time with straightforward serial data output
• Compact design fits into custom enclosures and products
• Reliable detection and stable performance suitable for production and prototyping

Getting Started (Basic Wiring and Code Tips)

1. Power the module with 3.3V to 5V and connect ground to the microcontroller ground.
2. Connect RDM6300 TX to your microcontroller RX and RDM6300 RX to microcontroller TX (if needed).
3. Open a serial port at the module’s baud rate and read incoming UID packets when a card is presented.
4. Use the UID string to authenticate users, trigger relays, log events, or integrate with your application logic.

Why Choose RDM6300 for RFID Projects

The RDM6300 provides a balance of affordability, compatibility, and ease of use. Its 125kHz RFID support, UART interface, and voltage flexibility make it a go-to choice for makers, system integrators, and small-scale deployments where proximity identification is required.
