Stereo Audio Amplifier Circuit

Whether it’s for your home entertainment system, DIY project, or a portable speaker, building an audio amplifier can significantly improve the quality and volume of your sound. In this blog post, we’ll guide you through the process of creating an audio amplifier using a ready-made module and dual 3W speakers, so you can enjoy high-quality audio without the need for complex circuitry. Before we dive into the project, let’s briefly discuss audio amplifiers. An audio amplifier, as the name suggests, amplifies audio signals, making them louder and more robust. It takes a low-power audio input and delivers a high-power output, which is crucial for driving speakers effectively.

PAM8403 – GF1002 3W+3W Dual channel audio amplifier board

This is a mini-board with a switching potentiometer. It contains powerful PAM8403 IC. Compact design allows it to easily fit inside many digital products. The working voltage is 5V. This board is built with a board switch potentiometer. This switch helps you to control volume and power switch freely. This board is best suited for portable devices. The sound output is also very good. You can easily connect two 3W speakers with this module.
