Questions
What parts does the Chua perfboard use?
11 parts. 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 Chua perfboard KiCad files?
From the byrantech/chua-circuit repository on GitHub, at the commit this page was made from: the board is chua-perfboard/chua-perfboard.kicad_pcb and its schematic chua-perfboard/chua-perfboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chua perfboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask byrantech before reusing the design.
