Questions
What parts does the Noob use?
7 parts, built around the NE555P. 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 Noob KiCad files?
From the AbhishekThomas91/pcbLearn repository on GitHub, at the commit this page was made from: the board is noob.kicad_pcb and its schematic noob.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noob design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
