Questions
What parts does the Esquematico use?
53 parts, built around the L7805. 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 Esquematico KiCad files?
From the Ramasantinofernandez/Cebador-de-mate repository on GitHub, at the commit this page was made from: the board is HARDWARE/esquematico.kicad_pcb and its schematic HARDWARE/esquematico.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esquematico design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ramasantinofernandez before reusing the design.
