Awesome 😎

The module is not actually a pam8403 , its based around some other chip, and that's the only con, apart from that pcb is really good quality for the price , it's power is 2.1w per channel not actually 3 , and the idle power consumption is really low like around 15ma idle , so it's really good for battery powered projects.

Good general purpose amplifier module.

I buy this amplifier module regularly, because of its performance and simple design. The module is so small and can be accommodated in very small spaces. It can be operated with battery as the voltage is very low. Only drawback is that we have to solder the external connections very carefully, otherwise the tracks will peel off.
