Questions
What parts does the Mateoyenciso7.5 9.18 use?
45 parts, built around the L7805 and BC547. 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 Mateoyenciso7.5 9.18 KiCad files?
From the Mateitolopez/Rel- repository on GitHub, at the commit this page was made from: the board is Hardware/mateoyenciso7.5_9.18.kicad_pcb and its schematic Hardware/enciso y mateo lopez/enciso y mateo lopez.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mateoyenciso7.5 9.18 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mateitolopez before reusing the design.
