From the project

Personal electronics and PCB projects created in KiCad with full documentation.

This project is a compact stereo audio amplifier PCB based on the TDA2822 audio power amplifier IC. The amplifier is configured in the standard stereo (single-ended) configuration, providing clean, low-noise audio for small speakers. The design includes an onboard analog volume control, a standard 3.5 mm auxiliary input, and AC-coupled speaker outputs suitable for general-purpose audio applications.
