Description
The EM-18 RFID Module is a compact, low-frequency RFID reader designed for quick integration into access control, automation, and identification systems.
It reads 125 kHz passive RFID cards and outputs the card’s unique 10-digit ID through TTL serial communication, making it extremely easy to use with microcontrollers such as Arduino, ESP32, PIC, AVR, and Raspberry Pi.
It includes an onboard antenna coil, dedicated decoder IC, and status LEDs, enabling plug-and-play operation with minimal external components.
PACKAGE INCLUDES:
- 1 × EM-18 RFID Reader Module
