Questions
How big is the PCB PCB?
It measures 76.8 × 33.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB use?
40 parts, built around the PAM8403DR, AMS1117-3.3 and AOD4184A. 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 PCB KiCad files?
From the Ontsmettinator3000/PCB repository on GitHub, at the commit this page was made from: the board is mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ontsmettinator3000 before reusing the design.
