DollaTek 3Pcs Electret Microphone Amplifier MAX4466 Module Adjustable Gain Blue Breakout Board for Arduino

About this item

• •Using introduction:
• •Connect GND to ground, VCC to 2.4-5VDC.
• •The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled).
• •If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device.
• •If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
• •The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier (such as 3.7W stereo amp)
• •If you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin.
• •For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.
• •Package Included:
• •3 x MAX4466 Electret Microphone Amplifier Module
