split_65 (insert creative name here) is a split, 65% layout keyboard designed for improved ergonomics and typing comfort over extended periods of time.
maybe grey's not your taste - red and green and blue, oh my!
It aims to remain loyal to the standard ansi layout, making the split_65 second nature to use. The sturdy two part aluminum construction ensures that the keyboard will survive whatever torture is thrown at it over the years
feels right at home on any desk

Questions
How big is the Split-65 PCB?
It measures 325 × 125 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split-65 use?
221 parts, built around the ATMEGA32U4-AU, PRTR5V0U2X and PJ-3200B-4A. 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-65 KiCad files?
From the samlli/Split-65 repository on GitHub, at the commit this page was made from: the board is pcb/split_65.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split-65 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).
