JMY620 is a series of RFID read/write module with UART and IIC communication port. JMY620 has various functions and supports multi ISO/IEC standard of ess card. 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.The module and antenna is split, so flexible antenna size and layout can be chosen. It connects outside antenna by 50ohm coaxial cable. The surface mount and very small module size are fit to portable devices. The impedance between RF circuit and antenna was tuned by impedance analyzer, so it has exnt performance and stability. It is based on NXP MF RC522, MF RC523, PN512, so it is low power consumption, and also could be set RF output level.
