Questions
What parts does the Octotrode use?
30 parts, built around the 74HC14. 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 Octotrode KiCad files?
From the mossmann/octotrode repository on GitHub, at the commit this page was made from: the board is octotrode.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Octotrode design in my own project?
Its repository states no licence, so its author keeps all rights: ask mossmann before reusing the design.
