Questions
How big is the Amplifier PCB?
It measures 100.1 × 45.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Amplifier use?
24 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 Amplifier KiCad files?
From the theWickedWebDev/Modular-Synth repository on GitHub, at the commit this page was made from: the board is Audio Amplifier/amplifier.kicad_pcb and its schematic 00_BREAKOUTS/Breakout-AudioJack/AudioJack-Breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask theWickedWebDev before reusing the design.
