nice product and good finishing. not yet tested
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.
