Questions
How big is the Vik splitter PCB?
It measures 25 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vik splitter use?
7 parts. 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 Vik splitter KiCad files?
From the sadekbaroudi/vik repository on GitHub, at the commit this page was made from: the board is pcb/vik-splitter/vik-splitter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vik splitter design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
