Frequently Asked Questions

What is the communication interface of the RDM6300 module?

The RDM6300 module communicates via a UART TTL serial interface. It outputs decoded tag IDs as serial data at a default baud rate of 9600 bps, making it directly compatible with the serial ports of microcontrollers like Arduino, ESP32, and Raspberry Pi (using a logic level converter if needed).

What types of RFID tags are compatible with this reader?

This reader is designed for 125KHz passive RFID tags that use the EM4100 protocol or are compatible with it. It supports both read-only tags and read/write tags that follow this standard, which are commonly used in access control cards and key fobs.

How do I increase the read distance of the RDM6300 module?

The module supports an external antenna. By connecting a larger, properly tuned 125KHz antenna coil, you can significantly increase the read range beyond the default 20-50mm, potentially up to the maximum effective distance of 150mm. Ensure the antenna is matched to the 125KHz frequency for optimal performance.

What is the power requirement for the RDM6300?

The module requires a 5V DC power supply with a tolerance of ±5%. Under normal operation, it draws less than 50mA of current. It is important to provide a clean and stable 5V source to ensure reliable tag reading and communication.
