RFID Reader (125Khz - UART)

Overview

Unlock the potential of RFID technology with the MOKWN 125kHz RFID Reader Module. This compact and efficient reader is engineered for seamless integration with Arduino and other microcontroller platforms. Whether you're building an access control system, an attendance tracker, or a smart identification project, this module provides reliable, low-cost RFID reading capabilities. With a UART TTL interface, it's incredibly easy to connect and use, making it a staple for makers, students, and engineers in Egypt.

Key Features

• 125kHz RFID Reading: Specifically designed to read 125kHz RFID tags (EM4100, TK4100, and compatible).
• UART TTL Interface: Simple 4-pin connection (VCC, GND, TX, RX) for direct communication with microcontrollers.
• Wide Voltage Compatibility: Operates on 3-5V, making it compatible with both 3.3V and 5V logic systems.
• Effective Range: Reads tags from up to 7cm, suitable for close-proximity applications.
• Compact Design: Small footprint ideal for embedding into custom projects.
• Easy Integration: Works with Arduino libraries and example codes for quick prototyping.
