Questions
How big is the Basic Buck Converter PCB?
It measures 54 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Basic Buck Converter use?
15 parts, built around the NE555P and IRF3205. 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 Basic Buck Converter KiCad files?
From the arturferdi/Basic-Buck-Converter repository on GitHub, at the commit this page was made from: the board is Basic_Buck_Converter/Basic_Buck_Converter.kicad_pcb and its schematic Basic_Buck_Converter/Basic_Buck_Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Basic Buck Converter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
