Contactless IC card module NFC function jinmuyu jmy5051

  1 Introduction
Jmy5051 series is a compatible module of jmy505 series
The difference is that jmy5051 series uses NXP clrc663 RF chip, which has better performance and supports more types of cards
See the module function configuration table for details
Jmy5051 is a modular circuit in which the user sends commands through IIC or UART interface to complete the reading and writing of contactless IC card
Jmy5051 has a wide range of functions
It supports the operation of a variety of contactless IC cards, and supports cards from many different suppliers
The designer has classified and integrated the commands of contactless IC cards, so the commands issued by users to modules through IIC or UART are relatively simple, but they can complete the comprehensive operation of various contactless IC cards
The impedance analyzer is used to adjust the impedance between the RF circuit and the antenna to match the impedance, which can achieve very good read-write performance and very good stability
The radio frequency antenna and module of the jmy5051 are designed separately
The module and the antenna are directly connected by 50ohm coaxial cable
The length can reach 10m, which can still ensure a good reading and writing effect
In the user's design, the connection distance is generally 60cm, which can achieve the best performance and stability
