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.
