Description: Ready 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 microcontroller’s Analog to Digital converter. Unit comes fully assembled as shown. Works from 2.7V up to 5.5V.

This microphone was exactly what I needed to design a digital filter using an ARM processor. It worked on the first try without giving any problems at all. Great product!
It’s convenient to have a mic with the amp cleanly although I’ve been trying to make an intercom system with no success, not the mics fault of course , but I have yet to rate the audio quality. One thing I can say is that the board itself is sturdy and forgiving with heat,when I soldered on the connections i was using an iron that got too hot and I had no experience with soldering so I spent some time with the iron very close to the board and connections and nothing was burned or damaged!
