Custom Split Keyboard
The PCBs for my custom split keyboard are available in this repository.
The PCB is made for hotswap switches compatible with the Choc v1 or v2 footprint. The first unique part about this is that it only uses one MCU and connects the two sides with a miniHDMI cable. The other unique thing is that it has arrow keys.

|---|---|
Roadmap for future versions
- Rethink the key layout
- Are the arrow keys really needed?
- Wireless (partially or completely using the nice!nano)
- LEDs for the wired version
- Display for the wireless version (nice!view or e-paper)

Questions
How big is the Right PCB?
It measures 173.8 × 173.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Right use?
76 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 Right KiCad files?
From the TheBlckbird/custom-split-keyboard repository on GitHub, at the commit this page was made from: the board is right/right.kicad_pcb and its schematic left/left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Right design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
