RFID Reader 125KHz Serial and TTL output

RFID Reader 125KHz Serial and TTL output 

The 125KHz RFID Reader with Serial and TTL Output is a compact and reliable contactless RFID reading module designed for embedded systems, microcontroller projects, and access control applications. It operates at 125KHz frequency and supports standard 125KHz RFID cards and key fobs.

This reader provides both TTL-level UART output and RS232 serial output, making it easy to interface with Arduino, Raspberry Pi, PLCs, PCs, and other microcontrollers. When a card is presented, the module reads the unique ID and transmits it through the serial interface automatically.

With fast response, stable performance, and simple integration, this RFID reader module is ideal for security systems, identification projects, and automation applications.
