The PAM8403 Digital Audio Amplifier Module is a tiny, efficient class-D stereo amplifier board built around the PAM8403 IC, delivering 2 x 3W of audio output from a low-voltage DC supply. It’s a popular choice for powering small speakers in portable audio projects and Arduino-based sound systems.

Key features:

  • Amplifier IC: Built around the PAM8403 dual-channel class-D audio amplifier chip.
  • Output Power: Delivers 2 x 3W of stereo output into 4Ω speakers.
  • Supply Voltage: Operates from 2.5V to 5V DC, making it easy to power from USB or batteries.
  • High Efficiency: Class-D switching design keeps heat low without needing a heatsink.
  • Compact Size: Its tiny footprint fits easily into small enclosures and portable builds.
  • Low Noise Output: Filterless design with low total harmonic distortion for clean sound.

Simply feed it a stereo line-level input and connect two small speakers to get instant amplified audio.
