When you need a little extra noise in your projects, these amps do a fine job and sized to fit in some really small projects.

Pretty good, the sound quality it's nice, but it would be nice to add the pot or the holes for it

Ordered for my C.H.I.P.

A perfect companion to the pocket C.H.I.P., allowed me to have a speaker and not need to use headphones.

This little amplifier module really packs a good punch. Decent sound quality for smaller diy boombox projects. I'd buy again.

Good and as described

Works as described, even works on a Li-ion battery. I am using it on a bluetooth system, so it could be louder. Drives my 3w speakers sufficently.
