RFID FDX-B Animal Tag Reader Module UART EM4305 134.2KHz
RFID FDX-B Animal Tag Reader Module UART EM4305 134.2KHz
RFID FDX-B Animal Tag Reader Module – UART Interface, 134.2KHz EM4305 Compatible
The LIHTNE 134-3R RFID Animal Tag Reader Module is a compact, easy-to-integrate solution for reading FDX-B animal identification tags using the EM4305 chip. Designed for developers, hobbyists, and OEM integrators working with livestock tracking, pet microchip verification, or embedded systems, this module outputs clean UART data for seamless integration with microcontrollers and single-board computers.
Important Notice: When tested with an oscilloscope, the antenna on this module operates at 125kHz — this is intentional. It is a cost-effective design that replaces the 134.2kHz carrier with a 125kHz antenna to read FDX-B protocol tags using the EM4305 chip. This module is only compatible with EM4305-based FDX-B tags. If your tag chip is not EM4305-FDX, this module is not suitable for your application.

Technical Notes
The module communicates via a standard UART serial interface at 9600 baud (No parity, 8 data bits, 1 stop bit), making it easy to connect to virtually any microcontroller or development board. Data is output as a 16-character Hex ASCII string for straightforward parsing.

Made in Mainland China.
Frequently Asked Questions
Q: Is this RFID animal tag reader module compatible with all FDX-B tags?
A: No — this module is specifically designed to work with EM4305-based FDX-B tags only. While it follows the FDX-B protocol, its antenna operates at 125kHz instead of the standard 134.2kHz. If your tag chip is not an EM4305, this module will not read it reliably. Please verify your tag's chip type before purchasing.
Q: What interface does this RFID reader module use, and how do I connect it?
A: The module uses a standard UART serial interface (9600 baud, No parity, 8 data bits, 1 stop bit). It can be connected directly to a microcontroller's TX/RX pins (e.g., Arduino, ESP32, Raspberry Pi). The module operates at 5V and draws approximately 25mA. A wiring diagram is included with the module to simplify setup.
Q: What is the read range of this FDX-B animal tag reader?
A: The read distance is approximately 4cm for 2×12mm glass tube tags and 3cm for 1.5×8.5mm glass tube tags. These are reference values and actual performance may vary depending on environmental factors, antenna orientation, and tag placement.
Q: What data format does the module output?
A: The module outputs tag data as a 16-character Hex ASCII code over the UART interface, making it easy to parse programmatically in any language that supports serial communication.
