An ergonomic, minimal, and fully-featured keymap for the Chocofi 36-key split keyboard (RP2040).
Built on the principles of Miryoku — efficiency, symmetry, and minimal finger movement.
- 🧠 Miryoku principles: use layers instead of reaches, home-row mods, mirrored thumbs
- 🎯 6 Layers: Base, Nav, Num, Sym, Fun, Mouse
- 🪄 Combos & Macros: for navigation, undo/redo, Esc, Enter, and more
- ⚡ Behaviors: dual-function thumbs (tap for key, hold for layer), conditional layers
- 🔋 Optimized for wireless RP2040 builds with battery and display support
- 💻 Editable via Keymap Editor
- 🧩 Faithful Miryoku port for ZMK (not QMK), adapted for Chocofi
This repository provides a ready-to-use Miryoku layout for the Chocofi 36-key split keyboard, built on ZMK and fully compatible with the Keymap Editor.
It removes the need to manually adapt Miryoku’s QMK or ZMK templates and makes customization accessible through a visual editor, while staying 100% faithful to the original Miryoku philosophy and structure.
Base Layer (Colemak-DH)
Home-row mods on both hands; thumbs control layers and key functions.
