Questions
What parts does the 12 V regulator use?
5 parts, built around the LM2596S-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 12 V regulator KiCad files?
From the khikidman/CUASC2027 repository on GitHub, at the commit this page was made from: the board is KiCAD/22v2_power_distribution_board/12 V regulator/12 V regulator.kicad_pcb and its schematic KiCAD/22v2_power_distribution_board/12 V regulator/12 V regulator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 12 V regulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask khikidman before reusing the design.
