ADMP401 MEMS Microphone Breakout Module Board For Arduino 1.3cm*1cm
Features :
This tiny breakout board features the ADMP401 MEMs microphone.
One of the key advantages of this breakout and microphone is the bottom ported input, which 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 more than 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-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels.
