DFRobot Fermion MEMS Microphone Module

DFRobot Fermion MEMS Microphone Module is a tiny MEMS microphone that has an amplifier gain of 66. It outputs voltage around 0.66 VCC when there is no sound detected. 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.
