The PAM8403 Audio Amplifier Module with Volume Control is a compact stereo Class-D amplifier board built around the PAM8403 chip, delivering clear, efficient sound from a low-voltage power source. An onboard potentiometer lets you adjust the volume directly on the board without any extra wiring.
Key features:
- PAM8403 Class-D IC: A high-efficiency 2-channel amplifier chip that runs cool and wastes very little power as heat.
- Onboard Volume Control: A built-in potentiometer adjusts output level directly, with no external pot or extra components needed.
- Stereo Output: Drives two speakers independently, making it suitable for small stereo audio projects.
- Low Voltage Operation: Runs from a single 5V USB or battery supply, ideal for portable and battery-powered builds.
- USB Power Input: Accepts power directly from a USB port or power bank via the onboard USB connector.
- Compact Size: Small footprint fits easily inside DIY speaker enclosures, robots, and portable audio gadgets.
It’s a popular, low-cost choice for adding amplified stereo sound to Arduino, Raspberry Pi, and other DIY electronics projects.
