Questions
How big is the Vik universal PCB?
It measures 44.5 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vik universal use?
154 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 universal KiCad files?
From the sadekbaroudi/vik repository on GitHub, at the commit this page was made from: the board is pcb/vik-universal/jumper-input-output-matrix/vik-universal.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vik universal 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).
