Questions
How big is the Sepic PCB?
It measures 45.7 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sepic use?
52 parts, built around the LT1370CR, JUMPER3 and V8PAN50-M3. 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 Sepic KiCad files?
From the frep/kicad repository on GitHub, at the commit this page was made from: the board is projects/Sepic/Sepic.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sepic design in my own project?
Its repository states no licence, so its author keeps all rights: ask frep before reusing the design.
