13.56MHz RFID card reader module with IIC or UART interface

YST304 series are RFID reader/writer module which pick or send command by UART and IIC ports. YST304 series meet kinds of international contactless IC card standards. Also YST304 series can support kinds of cards from suppliers. YST304 series RF antenna is separated from the module. The module is connected to the antenna by the 50ohm cable. It is with flexible antenna size and layout. The RFID module can be very good at reading/writing and very stable for impedance analyzer adjusting between RF circuit and antenna.

Characters:

The module is connected to the antenna by the 50ohm cable. It is with flexible antenna size and layout.
