Questions
What parts does the Mcuwith3subsheet use?
40 parts, built around the ARDUINO UNO R3 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 Mcuwith3subsheet KiCad files?
From the karthikkrishnaa/Internship1_PCB_files repository on GitHub, at the commit this page was made from: the board is mcuwith3subsheet/mcuwith3subsheet.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mcuwith3subsheet design in my own project?
Its repository states no licence, so its author keeps all rights: ask karthikkrishnaa before reusing the design.
