PAM8403 Class D Audio Amplifier

I bought 5 of these amplifier boards from an Ebay seller for $6.55 which included shipping from Hong Kong.

At only $1.31 per finished amplifier, I could not come close to building an amplifier for that price whether class D or not. They even have pads for a mute switch.

As you can see, they are very small; half the size of a 9v battery. The amps are stereo and rated for 3 watts per channel when powered by 5 volts.

I just received them so I have not wired one up for testing, but at that price, there is not much at risk.

Great little amplifier. Works great with line output such as ipod. I use them for smart phone docking stations.

Power with 5v usb or 3 AAA cells as >6V will burn it up.
