This RFID device reads the ID of the popular RFID tags running in the 125 kHz band (EM4102/4200). Each tag has its own unique identification number, which is sent as a 14-byte ASCII string via the RS232 interface.
LEDs and Buzzer are powered by internal voltage regulator. LEDs and Buzzer are activated by connecting the appropriate wire to GND. No external resistors required.
Note: In comparison to the 1-Wire RFID readers, there is no DS1990 emulation with this device.
