2.Layout principles
The distance between the microphone and the module's audio input should be as short as possible.
The microphone to module audio input wiring should avoid high-frequency pulse signals or high voltage from other external devices as much as possible.
The distance from the module's audio output to the external speaker should be as short as possible.
Note the schematic diagram of the layout of the components around the module.
