Questions
How big is the PowerRail PCB?
It measures 43.2 × 43.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PowerRail use?
65 parts, built around the VEC2616-TL-W. 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 PowerRail KiCad files?
From the engstad/PowerRail repository on GitHub, at the commit this page was made from: the board is PowerRail.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerRail design in my own project?
Its repository states no licence, so its author keeps all rights: ask engstad before reusing the design.
