DFRobot Fermion MEMS Microphone Module Signal Type: Analog signal Power Supply: 3.3 V / 5 V Sensitivity: -42 dB S/N Ratio: 59 dBA Frequency Range: 100 Hz ~ 8 KHz The DFRobot Fermio n MEMS Microphone Module has an amplifier gain of 66. When there is no sound detected, it outputs voltage around 0.66*VCC. 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. Show more
