Description
The HKD PAM8403 Audio Power Amplifier Board is a compact, high-efficiency Class-D stereo amplifier module designed for DIY audio projects, portable speakers, and embedded systems. Powered by just 5V DC, this tiny yet powerful board delivers up to 3W per channel of clear, distortion-free sound, making it ideal for small speaker systems where space and power efficiency are critical.
Built around the PAM8403 digital amplifier IC, this module ensures low noise, high-definition sound output, and stable performance with minimal heat generation. It comes with an integrated potentiometer knob that functions as both a volume control and power switch, allowing easy adjustment without the need for external controls.
Its small PCB footprint and USB power compatibility make it especially suited for DIY speaker projects, MP3 players, Arduino applications, and battery-powered audio systems.
