Overview
Split keeb v2 is an open-source printed circuit board by lordbagel42, from the lordbagel42/pocketable repository on GitHub. It is a 2-layer board of 330.5 × 136.1 mm with 138 parts on 108 nets, routed with 708 tracks and 4 vias.
It is built around the SK6812MINI-E. Its parts include 66 diodes, 4 resistors, 2 ICs, 2 connectors and 2 switches. It belongs with the keyboards and input boards and the nRF52 and nRF5x boards of this library.

ignore the fact that some of the keycaps are shiny and others are matte. blender is not happy with me.
if a corne and a zsa voyager had a child_
This project was made for one primary reason: my old split keyboard design kinda sucked to make layouts for. The thumb cluster was horrible. This, however, will function with ZSA Voyager layouts, which are generally shared publicly and well-tested.
This will be for sale eventually. Please reply to issue 1 if you would like to buy one. Cost will be around $240 per keyboard.
but why?
This keyboards a little special compared to most, for one reason: it's almost all made in-house by me. I'll be machining the brass plate myself along with the wooden base case, plus laser-cutting the acrylic LED cover myself. It's also all hand soldered and one day will have custom keycaps. For now though I've been graciously sponsored with black keycaps.
BOM
View the BOM at this google sheet. Total cost at time of writing this README is ~$250
more photos :3
heres the pcb design!
silkscreen art will be included for mine, however I won't be showing it in this repo as it contains a lil PII :3

Questions
How big is the Split keeb v2 PCB?
It measures 330.5 × 136.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split keeb v2 use?
138 parts, built around the SK6812MINI-E. 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 keeb v2 KiCad files?
From the lordbagel42/pocketable repository on GitHub, at the commit this page was made from: the board is PCB/split-keeb-v2.kicad_pcb and its schematic PCB/half.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split keeb v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lordbagel42 before reusing the design.
