JMY506 series are RFID reader/writer modulewith UART and IIC serial ports. JMY506 has various functions andsupports multi ISO/IEC standard of contactless card; the cards fromdifferent suppliers. The RF protocol is complex. But the designercombined some frequent used command of RF card and then user couldoperate the cards with full function by sending simple command to themodule through IIC or UART interface. And the module and antenna areseparate design. The impedance between RF module and antenna was tunedby impedance analyzer. And then the module has excellent performance andstability. The module and antenna is linked by 50ohm coaxial line. Theperformance is good, though the wire can reach 10m. Normally the wireshould be 60cm that is the module's best performance and stability.
