EM18 RFID 125KHZ RS232 OUTPUT WITH 2PCS 125KHZ RFID CARDS

EM18 RFID 125KHZ RS232 Output The EM-18 RFID reader is a popular choice for reading 125 KHz tags. It offers both UART and Wiegand26 output options. Additionally, the EM18 RFID development board has a TTL output, making it compatible with 5V microcontrollers like the Arduino Uno. An onboard buzzer indicates successful card reading or any errors. For power supply, simply use a 5v to 12V DC adapter with the onboard DC Jack. This device offers the convenience of being compatible with both microcontrollers via UART and PCs through an RS232 converter for direct interfacing. Key characteristics of EM18 RFID 125KHZ RS232 Output: The output of TTL. The buzzer located on the board. The power jack supports a range of -5v to 12v. The reading distance range falls within 4 cm.
