Fermion: MEMS Microphone Module

SKU: SEN0487

This tiny MEMS microphone has an amplifier gain of 66. When there is no sound detected, it outputs voltage around 1.5V. When speaking, you can easily get the acoustic waveform by ADC sampling. The module can be used on all kinds of 3.3V/5V main-controllers.
