The board:
Updates
- REBUILDING THE DESIGN FROM THE GROUND UP I didn't really like where I was going with this keyboard design and wanted to change the overall look and feel of the keyboard and the features that I want with this board
Features
- Hotswappable with mx-style switches
- Flippable PCB
- 4 Key Thumb Cluster
TODO
- Finish layout (ergogen)
- Make keyboard outline (ergogen)
- Create pcb (ergogen)
Goals
- Have hotswap with choc, kailh box etc.
- Be wireless
- Have RGB if I can actually configure it properly

Questions
How big is the Flow PCB?
It measures 167.4 × 148.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flow use?
68 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 Flow KiCad files?
From the scaarix/flow-keyboard repository on GitHub, at the commit this page was made from: the board is PCB/flow.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flow design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
