Yuburoll, designer of keyboards like the Modubu, KeeNoard, and Boardloaf, shared the ANSIC, a 40-42 key split board with uniformly row-staggered Katana-ish layout.
I made a new split keyboard for my illustration, CAD, and scripting work: which frequently uses ctrl+Y, right B, and pinky ctrl in one hand. This has uniform row stagger (0.5u), because of reversible PCB within 100x100mm design. And this may not be very ergonomic, but does not make too inconvenient hand positioning for my work. That's why I named the keyboard "ANSIC" - repose in Korean – Yuburoll.
Features
- 40-42 keys, symmetric layout, split spacebar
- MX switches, hotswap
- Pro Micro footprint
- reversible, under-100x100 mm PCB for cheap manufacturing
- TRRS connectors
- 3D-printed case
This was meant to be Yuburoll's first wireless design. That said, as of my understanding, the PCB works only in wired mode currently.
