Questions
How big is the Buck PCB PCB?
It measures 143.5 × 129.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buck PCB use?
49 parts, built around the LAUNCHXL-F28379D, LM358AP, UCC5304DWVR and BU-P72930-2. 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 PCB KiCad files?
From the CollinObrien1/Custom-Buck-Converter repository on GitHub, at the commit this page was made from: the board is Buck_PCB- R3.0/Buck_PCB.kicad_pcb and its schematic Buck_PCB- R2.0/Buck_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buck PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask CollinObrien1 before reusing the design.
