Sell 13.56 MHz rfid module JMY502 IIC & UART

Description

JMY**2M is RFID reader/writer module with UART and IIC serial port. 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 separate design. 4 wires are linked the antenna and module. Normally the wire should be less than **0mm, or it will affect the module's performance and stability.
