125KHz RFID Reader Module

Easy to use RFID Reader Module with Serial Interface. The module supports two data formats, UART and Wiegand. You can select the one you want to use via a jumper. Set the jumper to UART side (labeled 'U' on PCB) to use UART mode. The UART data format is as follows.

• TTL output (5V), 9600baudrate, 8 data bits, 1 stop bit, and no verify bit.
