MAX9814 Arduino Compatible Microphone Amplifier

Product details of MAX9814 Arduino Compatible Microphone Amplifier
Microphone Amplifier ModuleIt allows you to listen at a normal level by amplifying the sound signals detected by the microphone in projects where sound levels are insufficient and distant sounds are desired to be detected. The maximum gain that can be achieved with this module is 60 decibels. By changing the Gain Pin, the raising rate can be adjusted to 40 or 50 decibels.
