Description

YST**3 series are RFID reader/writer module which pick or send command by UART and IIC ports. YST**3 series meet kinds of international contactless IC card standards. Also YST**3 series can support kinds of cards from suppliers. YST**3 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 **0mm, or it will affect the modules performance and stability.
