Key Features
- Class-D Efficiency: Up to 90% power efficiency means minimal heat generation, eliminating the need for bulky heatsinks and making it perfect for battery-powered projects.
- Integrated Volume Knob: Onboard potentiometer provides smooth, hands-on volume adjustment without requiring external controls or software.
- USB-Compatible 5V Operation: Runs directly from USB power banks, phone chargers, Arduino 5V pins, or any standard 5V DC source for maximum versatility.
- True Stereo Output: Dual-channel amplification drives two separate speakers for genuine left/right stereo sound separation.
- Filterless Design: PAM8403's filterless architecture reduces external component count, board size, and overall system cost.
- Built-In Protection: Thermal shutdown and short-circuit protection safeguard both the module and your speakers from damage.
- Ultra-Compact Footprint: Tiny PCB fits inside portable speaker enclosures, small robots, wearable devices, and tight project housings.
- Plug-and-Play Simplicity: Just connect power, audio input, and speakers - no additional driver circuits, capacitors, or configuration needed.
