Great little electret microphone amplifier breakout. Designed with a 20-20KHz electret microphone and Maxim MAX4466 for amplification. Also included is a samall trimmer pot to adjust the gain. This amplifier has very good power supply noise rejection. Ideal for projects such as voice changers, audio sampling/recording and any audio-reactive tasks that us FFT.
Easy to use – connect GND to ground, VCC to 2.4-5VDC and the audio waveform will come out from the OUT pin which will have DC bias of VCC/2. Add a 100uF capacitor between output pin and input of your device if your project requires AC coupled audio. For connecting to microcontroller – connect OUT pin to microcontroller ADC pin.
