Review on Acxico 5Pcs Mini PAM8403 DC 5V Power Audio Amplifier Board - Digital 2 Channel 3W+3W Power Amp Module with Volume Control Potentiometer by Robert Pearson
Great digital amplifier!
Like many others here I use them to build my own Bluetooth speakers by combining with small very cheap but excellent Chinese mp3 and bt boards. They offer superior performance and are unmatched in this performance and price range. Depending on the watts/ohms requirements of your speaker, swapping out the 10k resistors for 18k resistors can help reduce the amplifier's heat somewhat if needed. Try it and see. That's a great thing!
