Power up your compact sound projects with the XH-M179 mini audio amplifier module!

The XH-M179 Digital Audio Amplifier Module, powered by the highly efficient PAM8403 chip, is the ultimate solution for space-constrained electronics projects where sound quality cannot be compromised. This Class D integrated circuit delivers crisp 3W stereo output per channel without the need for bulky heatsinks, making it extremely power efficient.

It is perfect for DIY portable Bluetooth speakers, Arduino or Raspberry Pi audio projects, retro gaming console builds (like arcade cabinets or custom handhelds), and audio repairs in monitors or toys.

✨ Key Features

High-Efficiency Class D: Excellent noise cancellation and low electromagnetic interference (EMI) without wasting energy as heat.
Ultra-Compact Design: Fits perfectly into tight spaces, custom enclosures, or small electronic project boxes.
Versatile Power Options: Operates smoothly via a 5V USB port, a standard phone charger, or single-cell lithium batteries (3.7V).
Built-in Protection: Features internal short-circuit protection for added safety during your builds.
