Questions
How big is the Split-60 PCB?
It measures 173 × 106.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split-60 use?
175 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Split-60 KiCad files?
From the gwerbin/split-60 repository on GitHub, at the commit this page was made from: the board is Split 60.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split-60 design in my own project?
Its repository states no licence, so its author keeps all rights: ask gwerbin before reusing the design.
