Questions
What parts does the Function Generator use?
33 parts, built around the AD8001AN and PCF8574AP. 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 Function Generator KiCad files?
From the PrinceEeppakayal/Kicad repository on GitHub, at the commit this page was made from: the board is Function Generator/Function Generator.kicad_pcb and its schematic Function Generator/Function Generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Function Generator design in my own project?
Its repository states no licence, so its author keeps all rights: ask PrinceEeppakayal before reusing the design.
