Questions
How big is the Ykb skadi pcb PCB?
It measures 55.6 × 57.2 mm and has 2 copper layers, 1 mm thick.
What parts does the Ykb skadi pcb use?
74 parts, built around the TPS62840DLCR, BQ25185DLHR, MAX17048G+T10 and USBLC6-2SC6. 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 Ykb skadi pcb KiCad files?
From the YarmanKB/ykb-skadi-pcb repository on GitHub, at the commit this page was made from: the board is ykb-skadi-pcb.kicad_pcb and its schematic finger-board/finger-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ykb skadi pcb design in my own project?
Its repository publishes it under the Apache-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).
