- Highly customizable 60% ortho layout - "Plateless" o-ring mounting - 3D printable case - UDB Support

The PCB supports many different layout options for the bottom row, embracing 1u keys but also with some left and right 1.5u modifier options.

The board also supports use of 2u keys in the usual TAB, LSHIFT, DELETE, and ENTER locations to maintain familiarity and speed with these often used modifiers.
