Replacement:<\/strong>BOB-09964<\/a>. The new version has a few small value changes. This page is for reference only.<\/p>\n\nReady to add audio to your next project? This small breakout board couples a small electret microphone with a 100x opamp to amplify the sounds of voice, door knocks, etc loud enough to be picked up by a microcontrollers Analog to Digital converter. Unit comes fully assembled as shown. Works from 2.7V up to 5.5V.<\/p>\n\n
