ANSIC Yuburoll 's ANSIC is a uniformly row-staggered 40-42 key split keyboard.
KBD.news Published February 10, 2026
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.
