    This small breakout board couples a small electret microphone with a Texas Instruments OPA344 100x OpAmp to amplify the sounds of voice, door knocks, etc. loud enough to be picked up by a microcontroller's Analog-to-Digital converter. The board comes fully assembled as shown, and works from 2.7V up to 5.5V.
