Questions
How big is the Spkb PCB?
It measures 153.2 × 154.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spkb use?
63 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 Spkb KiCad files?
From the llmerlos/spkb repository on GitHub, at the commit this page was made from: the board is SPKB/SPKB.kicad_pcb and its schematic SPKB/SPKB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spkb design in my own project?
Its repository states no licence, so its author keeps all rights: ask llmerlos before reusing the design.
