SeeedGrove 125kHz RFID Reader
Overview
The Grove 125kHz RFID Reader is a modular sensor designed for reading EM4100 series tags at a distance of up to 7cm. It simplifies the integration of radio-frequency identification into projects by providing both UART and Wiegand interfaces through the standard Grove connection system.
Why Choose This Part
This module operates on a standard 5V supply and features a compact 24mm by 44mm footprint. The dual-interface support allows engineers to choose between a simple UART serial output or the industry-standard Wiegand protocol for wider hardware compatibility.
Applications
Key Specifications
Getting Started
Connect the module to a Grove-compatible base shield and use a serial terminal or microcontroller UART to read the 10-digit ID codes from tags. It requires a 4.75V to 5.25V power supply and is compatible with standard Arduino libraries for serial communication.
