Jmy601 is based on nxp mf rc531, sl rc400, or cl rc632 chip design. It supports uart or iic interface and fully compatible with iso14443 type a and iso14443 type b and iso15693 protocols. The dimension is 60mm * 60mm * 5.7mm. Description Jmy601 is a series of rfid read/write module with uart or iic communication port. It has various functions and supports multi iso/iec standard of contactless 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 integrated. The impedance between rf circuit and antenna was tuned by impedance analyzer, and then the module has excellent performance and stability. Main characteristics Modules integrated antenna, excellent consistency and stability light and slim rf protocol in accordance with emv2010 Qualifications Pcd: nxp mf rc531, sl rc400, cl rc632 Pcb layers4 Working frequency: 13.56mhz Termsed standard: iso14443a, iso14443b, iso15693 anti collision ability: full function anti collision; be able to set multi-cards or single card auto detecting card: termsed, default off, could be set
