Super Bass Amplifier Using PAM8403 Board With MP3 Bluetooth
In this video I show how to make a Bluetooth speaker using the pam8403 amplifier module and mp3 bluetooth
The input voltage of Bluetooth mp3 is 12 volts, but it is reduced to 5 volts by regulator 7805. You can also use a voltage of 5 volts, which is equal to the voltage of the amplifier.

The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.
