This fully assembled and\n\u003cbr\u003etested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the\u003cbr\u003e\nMaxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power\n\u003cbr\u003esupply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other\n\u003cbr\u003emic amp breakouts we've tried!\u003cbr\u003e\nThis breakout is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can\u003cbr\u003eset the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6\"\u003cbr\u003eaway) which is good for attaching to something that expects 'line level' input without clipping, or up to\u003cbr\u003eabout 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets\u003cbr\u003eloud, the output can go up to 5Vpp!\u003cbr\u003eUsing it is simple:\u003cbr\u003eConnect GND to ground, VCC to 2.4-5VDC.\u003cbr\u003eFor the best performance, use the \"quietest\" supply available (on an for Arduino, this would be the 3.3V supply).\u003cbr\u003eThe audio waveform will come out of the OUT pin. The output will have a DC bias of VCC\/2 so when its\u003cbr\u003eperfectly quiet, the voltage will be a steady VCC\/2 volts (it is DC coupled). If the audio equipment you're using\u003cbr\u003erequires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If\u003cbr\u003eyou're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the\u003cbr\u003e100uF cap is not required.\u003cbr\u003eThe output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need\u003cbr\u003ean audio amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you're\u003cbr\u003econnecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT\u003cbr\u003epin directly to the microcontroller ADC pin.\u003cbr\u003eFor audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into\u003cbr\u003efrequencies. \u003ch3\u003e max9814\u003c\/h3\u003e\n\u003ch3\u003eThe MAX9814 is a low-cost, high-performance microphone amplifier with automatic gain control (AGC) and low-noise microphone bias.
