Questions
How big is the Audio Amplifier PCB?
It measures 69 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio Amplifier use?
13 parts, built around the LM386. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Audio Amplifier KiCad files?
From the YTHasib/PCB-Projects repository on GitHub, at the commit this page was made from: the board is PCB DESIGN PROJECTS/Audio Amplifier/Audio Amplifier.kicad_pcb and its schematic PCB DESIGN PROJECTS/Audio Amplifier/Audio Amplifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask YTHasib before reusing the design.
