Hmmm.. Let’s add some audio to the project of yours and make the world dance. This small breakout board is very interesting since it couples a small electret microphone with a 100x opamp to amplify the sounds of voice, door knocks, things like that in which are considered loud enough to be picked up by a microcontroller's Analog to Digital converter.
Note that it works from 2.7V up to 5.5V, also, it comes fully assembled and ready just as shown.
Now available in Dubai, UAE, Oman, and Qatar.
