Crowtail MEMS MIKROFONI 2.0

The Crowtail- MEMS Microphone is a simple and easy-to-use microphone for a variety of sound-sensing projects. The on-board mic is an ADMP401, which is a low-power, omnidirectional microphone with an analog output. The amplifier’s AUD output will float at one half Vcc when no sound is being picked up. The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels. So the AUD output can easily be connected to the ADC of a micro.
