Split keyboard. Ortholinear grid with column stagger. Built for comfort and long sessions.

Tao Te Ching is a split mechanical keyboard that combines the predictability of ortholinear rows with the ergonomics of column stagger. Each half is compact, symmetric, and designed to keep hands in a neutral position.

This will be my first split keyboard. Ive seen many people make splits. But nearly noone uses custom layout. So I made this layout.

You can write up a simple firmware or use the KMK script in my repo.

• Split, mirrored halves
• Ortholinear rows with column stagger
• Compact layout with outer thumb/utility keys
• Optimized for touch typing and minimal finger travel

See renders and PCB files for exact spacing and geometry.

• MX-compatible switches
• Per-key diodes (matrix)
• Controller footprint suitable for XIAO-class boards
• Board-to-board connection pads for split communication

Plates can be 3D-printed (PLA works) or CNCed.

• QMK / KMK / ZMK (controller-dependent) I will use KMKK
