Questions
How big is the 36 split PCB?
It measures 127.5 × 98.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 36 split use?
49 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 36 split KiCad files?
From the wj-zhe/awkb repository on GitHub, at the commit this page was made from: the board is hardware/36/rev2/PCB/36_split.kicad_pcb and its schematic hardware/34/monosplit_rev1/pcb/34_monosplit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 36 split design in my own project?
Its repository states no licence, so its author keeps all rights: ask wj-zhe before reusing the design.
