JMY5041 is the second generation product based on JMY504 with UART and IIC serial port.JMY5041 has various functions and supports multi ISO/IEC standard of contactless card. The RFprotocol is complex. The designer combined some frequent used command of RF card and then usercould operate the cards with full function by sending simple command to the module.
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 split design. 4 wires are linked the antenna and module. Normally the wire should be less than 200mm, or it will affect the module’s performance and stability.
