Instruction:

RDM881 Series module is a contactless smart card reading and writing module developed based on ISO18092,ISO14443A/B international standard protocols. It adopts highly integrated special card reading chip PN532, advanced watchdog and voltage monitoring circuit project design and features a high degree of integration, strong anti-interference ability, small size and more stable performance. Provides the underlying communication protocol, to facilitate the secondary development of client applications.Same with the RDM880(13.56MHz) module size and pin definition; and hardware can be replaced directly.
