| Message: | YST303 series are RFID reader/writer module which pick or send command by UART and IIC ports. YST303 series meet kinds of international contactless IC card standards. Also YST303 series can support kinds of cards from suppliers. YST303 series RF antenna is separated from the module. The RFID module can be very good at reading/writing and very stable for impedance analyzer adjusting between RF circuit and antenna.4wires are linked the antenna and module. Normally the wire should be less than 200mm, or it will affect the module’s performance and stability.
