Layout
Each half of the board is a 4x6 matrix with the same vertical stagger as the Ergodox and with 3-4 thumb keys. The 2u thumb key can be replaced with 2 1u keys. The spot for the 2u has holes for Cherry PCB mounted stabilizers. Alternatively, a rotary encoder can be placed at the upper thumb key of each half.
Many thanks to Lewis Ridden (/u/GAMING_FACE) for coming up with this design.
