You can set the gain from 25x to 125x. That's down to be about 200mVpp\n(for normal speaking volume about 6\" away) which is good for attaching to\nsomething that expects 'line level' input without clipping, or up to about\n1Vpp, ideal for reading from a microcontroller ADC. Using introduction:\nConnect GND to ground, VCC to 2.4-5VDC. The audio waveform will come out of\nthe OUT pin. The output will have a DC bias of VCC\/2 so when its perfectly\nquiet, the voltage will be a steady VCC\/2 volts (it is DC coupled). If the\naudio equipment you're using requires AC coupled audio, place a 100uF\ncapacitor between the output pin and the input of your device. If you're\nconnecting to an audio amplifier that has differential inputs or includes\ndecoupling capacitors, the 100uF cap is not required. The output pin is not\ndesigned to drive speakers or anything but the smallest in-ear headphones-\nyou'll need an audio amplifier (such as 3.7W stereo amp) If you want to\nconnect the amp directly to speakers. If you're connecting to a\nmicrocontroller pin, you don't need an amplifier or decoupling capacitor -\nconnect the OUT pin directly to the microcontroller ADC pin. For audio-\nreactive projects, we suggest using an FFT driver library which can take the\naudio input and 'translate' it into frequencies.

This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on.\u003c\/li\u003e\n\u003cli\u003eFor the amplification, we use the MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried!\u003c\/li\u003e\n\u003cli\u003eThis breakout is best used for projects such as voice changers, audio recording\/sampling, and audio-reactive projects that use FFT.\u003c\/li\u003e\n\u003cli\u003eOn the back, we include a small trimmer pot to adjust the gain.

For the best performance, use the \"quietest\" supply available (on an Arduino, this would be the 3.3V supply). 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).\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n\n ","brand":"NOYITO","offers":[{"title":"Default Title","offer_id":41839079194804,"sku":"B07HFSRGSG","price":115.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/products\/B07HFSRGSG.jpg?v=1662620189","url":"https:\/\/auspowers.com\/products\/noyito-max4466-electret-microphone-amplifier-adjustable-gain-pack-of-2","provider":"AusPower Australia","version":"1.0","type":"link"}
