README
README.mdSpan keyboard
Span is a low profile split keyboard with 3x5 column staggered keys with 2u, 1.5u, 1u thumb clusters.
The keyboard layout is derived from GergoPlex, a keyboard that was originally available on gboards.ca (now defunct).
Features:
- 18x17 mm choc spacing.
- Optional 2u choc stabilizer.
- OLED support.
- Hybrid hotswap / direct soldering for switches.
The pcbs aren't reversible at the moment: I prefer the cleaner look of the top side and generally think it's easier to deal with. A reversible version may be added in the future.
Availability
Kits and built keyboards can be purchased on holykeebs.

How big is the Span PCB?
It measures 232 × 95.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Span use?
96 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 Span KiCad files?
From the idank/spankbd repository on GitHub, at the commit this page was made from: the board is pcb/span.kicad_pcb and its schematic pcb/span.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Span design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
