Audio amplifier's circuit design#
The whole audio amplifier board's design was made in KiCad 7.0 (open-source software).
The design is made open and is fully explained in this article. Screenshots will be provided along with short descriptions.
The schematic#
For those interested to see the final circuit, here is the complete schematic:
An overview of the whole schematic of the final audio amplifier
In the following paragraphs, I will break down the most important parts of the circuit so that the overview above makes more sense.
Please note that the explanation is soon to come!
Selecting the components#
The real-world components need to be selected now. This is a simple process, but it requires trial and error and some experience.

As you can tell, I've completely open-sourced the board's circuit design. However, I do ask that you keep the name of the board and give me credit whenever you use the design.
