About JZX877:


JZX877 set parameters, the market is no longer used wireless modules used in the traditional way to 

change the parameters of the jumper, causing long-term use because it brings bad, options less dynamic 

change is not easy, a lot of inconvenience. JZX877 using the serial port setting parameters easy and 

quick, easy set refers to the chip embedded in the user program and operating software in the
