I am planning to connect a microphone to the MC20 module, I used the circuit suggested by the module documents, but there is a problem that the sound received from the microphone is weak and it is necessary to speak completely in front of the microphone for the sound to be heard.
Of course, this problem does not exist with the use of Bluetooth and hands-free functionality.
Now I need to know if it is possible to use the amplifier in the microphone input of the module? and whether there is a suggested circuit or not.
thanks to everyone
