Product Description

JMY**5 series are RFID reader/writer module with UART and IIC serial ports. JMY**5 has various functions and supports multi ISO/IEC standard of contactless card; the cards from different suppliers. The RF protocol is complex. But the designer combined some frequent used command of RF card and then user could operate the cards with full function by sending simple command to the module through IIC or UART interface. And the module and antenna are separate design. The impedance between RF module and antenna was tuned by impedance analyzer. And then the module has excellent performance and stability. The module and antenna is linked by *0ohm coaxial line. The performance is good, though the wire can reach *0m. Normally the wire should be *0cm that is the module's best performance and stability.
