The firmware, re-focused

Magnetic by design. Competitive by nature.

An open firmware foundation for magnetic gaming keyboards, with room for the project and its community to grow.

Made for magnetic switches

Tune actuation distance and Rapid Trigger sensitivity to shape how magnetic key travel becomes input.

Up to 8K polling

Up to 8,000 Hz USB polling, with a nominal 125 μs polling interval at 8K.

Competition comes first

Built with competitive performance in mind. Configure multi-stage commands, opposing-key behavior and analog gamepad input around the way you play.

Room to evolve

An open direction for different keyboard designs. Future directions may include other polling rates, such as 1K, and wireless connectivity as the project evolves.

Open source under GPL-3.0

MKF firmware uses the GPL-3.0 license. Explore the source, share ideas, and contribute improvements under the project’s license terms.

Open to the community

A place for keyboard developers, enthusiasts, and players to exchange ideas, contribute, and help shape what comes next.

Make every part of a key press count.

Tune triggering, combine commands and explore analog input. Discover the magnetic keyboard features supported by MKF.

Set the trigger. Tune the response.

Choose how far a key travels before it registers, and adjust Rapid Trigger sensitivity for repeated inputs as the key moves.

  • Actuation Distance — set the travel point that registers a key press.
  • Rapid Trigger — enable rapid triggering and adjust its sensitivity, with Basic and Advanced settings.
  • Trigger Demo and Test Keys let you inspect key behavior and input values.

More commands in one key’s travel.

Assign different commands to four stages of a key’s press and release. Build a sequence around the way you press and release a single key.

  • Four stages: Starting Trigger, Bottom In, Bottom Out and BounceBack.
  • Choose the commands and configure the trigger points in the settings interface.

Quick successive triggers from one press.

Use Long-Press Switch to trigger the selected key in quick succession with one press.

  • Choose the key and enable the function from its settings panel.
  • Manage the configured keys in the Keys Set list.

Choose how opposing inputs are resolved.

Set the behavior of paired opposing keys with Rappy Snappy, Last Key Priority, Absolute Priority or Neutral.

  • When both keys are pressed, Rappy Snappy compares their travel: the deeper key triggers while the other resets.
  • Select a mode and manage the paired keys in the bound-command list.

Bring analog gamepad input to your keys.

Map keyboard keys to sticks, triggers and gamepad buttons, with an effect preview to check the resulting input.

  • Choose the Standard Controller or Xbox Controller option.
  • Control whether keyboard typing and controller recognition are enabled.
  • Reconnect the keyboard after changing controller recognition settings for the changes to take effect.

Shape how travel becomes analog input.

Choose a response curve to change how key travel translates into analog output.

  • Linear and Smooth profiles provide two response options.
  • The curve display shows the relationship between travel and output.

Press deeper for more triggers.

PDO increases the number of triggers as you press the selected key deeper.

  • Configure the maximum trigger count for the selected key.
  • Manage enabled keys in the Keys Set list.

Repeat inputs at your chosen pace.

Produce continuous repeated input when pressing a selected key, and adjust the repeat settings.

  • Tune the repeat behavior with the Key Press Speed control.
  • Choose the keys that use Turbocharged and manage them in the settings list.

8K, explained

Up to 8K polling.
Room for what comes next.

At 8K, USB polling runs at a nominal 8,000 Hz — one polling opportunity every 125 microseconds. A performance highlight within a broader open-source firmware project.

Polling cadence illustration · Not a latency benchmark

8 kHz denotes a nominal 125 μs USB polling interval, not end-to-end input latency or keyboard scan rate. Actual performance and available rates depend on hardware, firmware, host, and configuration. 8K is a performance highlight; it does not define the project’s future polling rates or connection options.
