MNML Firmware Builds

MNML, pronounced minimal, is a family of integrated wireless split keyboards. The controller, power management, charging, battery reporting, and direct memory display support are built into the keyboard.

Available Firmware Targets

MNML 3×5 + 5M

Left target

clickety_split_mnml_3x5_left//zmk

Right target

clickety_split_mnml_3x5_right//zmk

Status: Physically validated through sustained bench testing and extended operational use.

MNML 3×6 + 5M

Left target

clickety_split_mnml_3x6_left//zmk

Right target

clickety_split_mnml_3x6_right//zmk

Status: Physically validated through sustained bench testing and extended operational use.

MNML 4×6 + 6M

Firmware targets: Not yet registered.

Status: In fabrication.

Local Build Example

From the ZMK workspace root:

west build -p -s app \
  -d build/mnml_3x5_left \
  -b clickety_split_mnml_3x5_left//zmk

Replace the build directory and board target with the matching layout and half.

Important Notes

  • Use the target matching the physical MNML layout and side.
  • Flash the matching left and right UF2 files.
  • The display and battery-reporting hardware are defined directly by the board.
  • Do not add separate hardware shields unless the product instructions explicitly require one.
  • A settings reset may be required when moving between materially different configurations.

Recommended Build Path

The public Clickety Split GitHub configuration and GitHub Actions workflow will be linked here after final validation of ZMK with Zephyr 4.1.
