(Any single-chip microcomputer, as long as it has a serial port (or IOport analog serial port), can be used together with the ZIGBEEtransparent transmission module. The serial port is used to send andreceive data and the serial port of the configuration module is 3.3V level,which can be directly connected with the 3.3V MCU. In the case of a 5Vmicrocontroller, level shifting is generally required.
