Questions
What parts does the BotCortex use?
61 parts, built around the BC237. 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 BotCortex KiCad files?
From the jochenalt/Walter repository on GitHub, at the commit this page was made from: the board is schematics/BotCortex/BotCortex.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BotCortex design in my own project?
Its repository states no licence, so its author keeps all rights: ask jochenalt before reusing the design.
