Questions
How big is the Miniamp PCB?
It measures 78.7 × 54.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Miniamp use?
29 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 Miniamp KiCad files?
From the blthree/synth_schematics repository on GitHub, at the commit this page was made from: the board is miniamp/miniamp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Miniamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask blthree before reusing the design.
