Default Keymap

The default keymap is shown in keymap-drawer/felix.svg.

The keymap source is located at config/felix.keymap, and the keyboard layout JSON is located at config/felix.json.

Key Remapping

You can remap the keyboard with the following tools:

• ZMK Studio
• Nick Coutsos Keymap Editor

The build configuration in this repository already includes the studio-rpc-usb-uart snippet required by ZMK Studio.

Firmware Build

GitHub Actions generates the build matrix from build.yaml. By default, it builds the following firmware files:

• felix_left nice_oled
• felix_right nice_oled
• settings_reset
• felix_left nice_view_adapter nice_epaper
• felix_right nice_view_adapter nice_epaper

Before flashing, choose the build artifact that matches your hardware version.
