It’s fine to have your project generate noise, but to be heard, you need more than just a larger speaker – you need muscle! This is where this PAM8302 breakout board from Adafruit comes into play. Throw 2 to 5VDC at it, and it will amplify your mono signal into 4~8 ohm speakers with 2.5 watts of authority.

In short, it’s a small, tidy module for making your small mono signal BIG.
