From the project
A 22-key column-staggered unibody split keyboard
UT22 is a 22 key column-staggered choc unibody keyboard that is intended to be used with the Artsey or Taipo layout. It's essentially a left and right handed artsey/taipo board in a single body with extra thumbs and pinky keys. It uses a Nice!Nano and the PCB supports a Nice!View display.
If you like to get a PCB to build your own UT22 you'll find the source files and a Gerber file here.
