The PAM8403 is a miniature stereo power amplifier board capable of delivering 3W per channel at 5V into 4Ω speakers with high efficiency (~90%). It features a potentiometer with integrated switch to control both volume and power, making it ideal for portable electronics and battery-powered devices. The board can be powered via USB (5V) or a suitable DC source. Users should ensure the operating voltage stays below 5.5V and avoid reversed connections, as the module lacks protection and can be damaged if incorrectly wired.
