Questions
How big is the Pcb-2 PCB?
It measures 147.9 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb-2 use?
44 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 Pcb-2 KiCad files?
From the rek/keyboards repository on GitHub, at the commit this page was made from: the board is 02/pcb-right-v2/pcb-2.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 Pcb-2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rek before reusing the design.
