From the project

Circuit schematics for the AK-280 audio amplifier, created using KiCad.

I have reverse-engineered the AK-280 purchased on Amazon Japan and created a schematic for it.

This project documents the hardware architecture for the purpose of deepening understanding of circuit structures as a hobby.

This repository contains schematic data created by tracing the print patterns and components of the AK-280 audio amplifier. KiCad was used to create the schematics.
