Questions
How big is the Splay PCB?
It measures 154.7 × 90.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Splay use?
53 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 Splay KiCad files?
From the rek/keyboards repository on GitHub, at the commit this page was made from: the board is 04/splay/splay.kicad_pcb and its schematic 02/pcb-left-v2/pcb-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Splay design in my own project?
Its repository states no licence, so its author keeps all rights: ask rek before reusing the design.
