Keymaps

NXTKB keyboards use ZMK (Zephyr-based Modular Keyboard) firmware. ZMK keymaps let you define what each key does, organize keys into switchable layers, and assign tap-hold behaviors — all through customizable configuration files.

Default Keymaps

Each NXTKB keyboard comes with a pre-configured keymap optimized for its layout:

• Ferris Sweep Pro Keymap
• Ferris Sweep Keymap

These pages contain visual layer diagrams and detailed explanations of each key function.

Customization

Want to change your keymap? See How to Update Keymaps for step-by-step instructions using ZMK Studio, the Keyboard Editor, or direct source code modification.
