Introduction JMY501 ??series is a user-by IIC or UART interface to send commands to complete a modular circuit for non-contact IC card reading and writing operations. JMY501 ??series features many, supports a variety of non-contact IC card international standards, to support a number of different suppliers cards. Designers of the non-contact IC card orders are classified package integration, so users IIC or UART command module issue is relatively simple, but was able to complete the full operation of the various non-contact IC card. JMY501 ??series between the RF antenna and module using split design, RF circuits and antennas using an impedance analyzer adjusted to match the impedance to achieve a very good read and write performance and very good stability. Module and antenna directly from the 4-wire connection, the user designs this link distances as short as possible, generally not more than 20cm, otherwise it will affect the performance and stability.
