JMY**1 series are RFID reader/writer module with UART and IIC
serial ports. JMY**1 has various functions and supports multi
ISO/IEC standard of contactless card; the cards from different
suppliers. 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. 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.
Qualifications:
• PCD: NXP RC**0
• Working frequency:
*3.*6MHz
• RF standard:
ISO****3
• Operating distance:
**0mm(depending on card and antenna design)
• Anti collision ability:
Full function anti collision; be able to process multi-cards
simultaneously; be able to set operate single card only
• Auto detecting card:
Supported, default OFF
• EEPROM: **2Bytes
• Interface: IIC &
UART (selected by SPS pin, recommend to use IIC)
• Communication rate:
