PAM8303 mini audio amplifier module with a knob
PAM8303 mini 3W mono Class-D audio amplifier module with onboard volume control knob, high efficiency, and low-voltage operation.
Description
The PAM8303 Mini Audio Amplifier Module with Knob is a compact and efficient Class-D mono audio amplifier designed to deliver clear sound output in small and portable projects. Based on the PAM8303 IC, this module provides up to 3W output power while maintaining high efficiency and low heat dissipation.
It features an onboard volume control knob, allowing easy manual adjustment of audio level without additional circuitry. The module operates on a 2.5V to 5.5V power supply, making it compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other low-voltage systems. Its filterless design simplifies wiring and reduces component count.
This amplifier module is ideal for portable speakers, voice announcement systems, IoT devices, toys, alarms, and DIY audio projects where compact size and ease of use are essential.
