Joy-iT MEMS microphone breakout board

This tiny breakout board features the ADMP401 MEMS microphone. One of the key advantages of this breakout and microphone is the bottom ported input. This means the microphone's input can fit flush against the enclosure of your project. The amplifier on the breakout has a gain of 67 and meets the bandwidth requirements of the mic.
The amplifier's AUD output will float at one half Vcc when no sound is being picked up. The amplifier produces a peak output of about 200mV when the microphone is held at arm's 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.
