pcb/README.mdImportant Stuff
- Planning on having m2 screws mounted through the switch mount plate then through the pcb and then inside the brass heat inserts mounted in the bottom case
- Clearance needed:
- 5mm : top of switch mount plate to top of pcb
- 3.3mm : top of pcb to bottom of mx pins
- 3mm : brass insert
- TOTAL : 11.3mm (ordering both)

Questions
How big is the Split PCB?
It measures 126.2 × 94.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split use?
27 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 Split KiCad files?
From the aditya23043/split36 repository on GitHub, at the commit this page was made from: the board is pcb/split.kicad_pcb and its schematic pcb/split.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
