Questions
How big is the Vregulator PCB?
It measures 31.8 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vregulator use?
289 parts, built around the TPS40304DRC and TPS75601KC. 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 Vregulator KiCad files?
From the dodotronix/FEEC repository on GitHub, at the commit this page was made from: the board is step-down-converter/Vregulator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vregulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask dodotronix before reusing the design.
