Questions
How big is the Buck conveter PCB?
It measures 92.7 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buck conveter use?
22 parts, built around the LM2596S-5.0, LM2596S-ADJ and LM2596T-12. 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 Buck conveter KiCad files?
From the UltraInstinct21/Kicad_Projects repository on GitHub, at the commit this page was made from: the board is 1.BUCK_CONVERTER/Buck_conveter.kicad_pcb and its schematic 1.BUCK_CONVERTER/Buck_conveter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buck conveter design in my own project?
Its repository states no licence, so its author keeps all rights: ask UltraInstinct21 before reusing the design.
