Max9814 Microphone Amplifier - Amplifier Module - Arduino Compatible

Max9814 High Performance Microphone AGC Amplifier Module CMA-4544PF-W

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.
