Questions
What parts does the My main files use?
57 parts, built around the ATMEGA8-16AU, AMS1117-3.3, 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 My main files KiCad files?
From the afrazali722/Io-Controller-PCB repository on GitHub, at the commit this page was made from: the board is my main files.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the My main files design in my own project?
Its repository states no licence, so its author keeps all rights: ask afrazali722 before reusing the design.
