PAM8403 Mini 5V Digital Amplifier Board With Switch Potentiometer
This is the PAM8403 Mini 5V Digital Amplifier Board with a Switch Potentiometer. The PAM8403 is a compact digital amplifier chip that delivers high-definition sound quality, showcasing the advantages of digital technology. The circuit features an optimized peripheral configuration, with upgraded power supply filtering using a 470μF capacitor (many sellers use less than 100μF).
Crafted from 1.6mm glass sheet, this amplifier board is designed for high-fidelity sound output, delivering 3W + 3W of power. It’s an excellent choice for audio enthusiasts. The potentiometer used is a high-quality anti-meter design, and it includes a switch that can cut off the power supply by turning counterclockwise.
Usage:
Ideal for battery-operated or portable electronic products, it’s suitable for long-term stable use.
Note:
Ensure the power supply does not exceed 5.5V, and avoid reversing the polarity of the “+” and “-” connections, as this may damage the board.
