Questions
How big is the Buck PCB?
It measures 18.7 × 12.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buck use?
13 parts, built around the TPMP2359DJ. 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 KiCad files?
From the CapnKernel/buck repository on GitHub, at the commit this page was made from: the board is buck.kicad_pcb and its schematic buck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buck design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
