5pcs Mini PAM8403 DC 5V 2 Channel USB Digital Power Amplifier Board Module 2 * 3W Volume Control with Potentionmeter

Excellent compact amplifier module for small projects. Used one of these with speakers to boost the sound from my PC. Minimal distortion, although a bit weak on the bass signals; not surprising for such a low-power package. Great for projects needing a moderate audio output. Simple to use.

I was surprised how well it works and how small it is.

I inherited one of those inexpensive record players. It was damaged because they hooked up the wrong power supply and fried the existing board. I used this board to replace the amplifier, and it worked. I'm surprised honestly by how well it actually works. We're talking 3 watt speakers, so it's only for personal listening but it worked out and made the record player at least able to play records again.

Worked great for repurposing a friend's old iMac tiny 8 ohm globe speakers. Hook up is dead simple, with much potential for putting to various creative uses.

Loud when used with Make Hawk Arduino Speaker 3 Watt 8 Ohm Single Cavity Mini Speaker. Used with the talkie library for voice on a arduino uno project, talking thermometer.

Tried to get one to work, never again!

I used this in an Arduino project, making a talking dog button board. If you are looking for a volume knob for these, it looks like this is course thread. I found these knobs work great : 4 Abalone Ring Black Les Paul Custom Control Speed Dial Knobs (Top Hat Clear Black) by Dinatone.

These do not get very loud, I seriously doubt the claimed wattage.
