The electronic of my old speaker was fried and it's lipo battery tired.
With this Pam8403 i transformed the speaker in wired amplified speaker to a little TV.
I add 4700uF capacitor for the five volts power supply.
This amplifier needs a good 2Amps or more power supply.
There is a power swith un the pot.
Good sounding microscopic audio amplifier.

Q:
After having tested this board, I find a strange ticking noice from the amplifier. When I doesnt attach this amplifier, or use another amplifier, there are no ticking noices. Do I have a faulty board, or is it normal to have ticking noice from this board? I used 3.3V as power, and an 8 ohm 0.3W speaker. It should not generate ticking noices.

Q:
I was thinking about using this as a headphone amp, but it would have to have a common ground on outputs. It doesn't look like that is the case. Is that correct?
