Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

After the first teaser (Rolio 0.1), MickiusMousius published the files of Rolio 0.9 – the same split with nice!view display and roller encoder, but with some tweaks.

I've recently uploaded the 0.9 design files of the Rolio keyboard, so far I'm pretty happy with it. There are just a few small improvements to get to a 1.0 release! – MickiusMousius.

Inspiration for this project came from the Corne and Sofle keyboards. The author has attempted to combine what he believes are the best aspects of both of these keyboards into a single project.



  • Low profile, Choc-spaced form factor (similar to Corne)
  • Fully wireless (Nice!Nano controllers and ZMK firmware)
  • Excellent battery life (2+ weeks before it gets to 60%)
  • Horizontal roller encoders on both halves
  • Backlight, efficient enough to be used on battery
  • Up to five memorized bluetooth profiles and a USB mode
  • A robust chassis "so that it can be treated like a normal keyboard"
  • An FDM version for at home low cost production
  • A CNC option for a slick look and premium feel
  • A travel case that can easily be made using any FDM printer


The keycaps in the photos are fully customized and match the ZMK keymap thanks to FKCaps.
