This RFID Reader module has a built–in antenna in minimized form factor. It is designed to work on the industry standard carrier frequency of 125KHZ.
This LF reader module with an internal or an external antenna facilitates communication with read-only transponder – type UNIQUE or TK5530 Via the air interface. The tag data is sent to the host systems via the wired communication interface with a protocol selected from the module both TTL and weigend protocol.
The LF module is best suited for application in access control, time and attendance, asset management , handheld readers, immobilizers and other RFID enabled application.
Connect – 5 volts and GND
TX- TTL output can be directly connected to microcontroller (To convert TTL to UART use converter board).
D0 & D1 - Is used for weigend protocol.
· Connected – 5Volts and GND
· Plugs and play , needs +5V to become a reader
· Buzzer indicates tag reading operation
· Compact size and cost effective.
