The Redox project repository

Redox logo QMK

The Redox project is an open-source, QMK (Quantum Mechanical Keyboard Firmware) powered, ergonomic split mechanical keyboard. This repository will be used to share information about the project and instruction on how to use and assembly the Redox keyboard.


Designer's bio: Mattia Dal Ben (aka u/TiaMaT102) obtained a master's degree in Electrical Engineering with a specialization in Computer Science at the University of Udine. Currently works as a Software Engineer in R&D department for a big IoT and Embedded Computers company. Mechanical keyboard enthusiast and maker, the Redox keyboard is the result of all of his passions.


The Redox is a keyboard project designed with ergonomics in mind. It uses Cherry MX style mechanical switches laid out in a 7x5 columnar stagger layout with components that can easily be sourced.

The design was heavily inspired by the Ergodox keyboard, and its main goal is to reduce the size without sacrificing too many keys, hence the name Reduced Ergodox.

As an Ergodox user I couldn't ignore the few flaws of the original design and in a moment of arrogance I tried to fix them, thus the Redox features:

  • Easier to reach thumb cluster.
  • Additional easy-to-reach rotated 1.25u thumb key.
  • Reduced size.
  • Reduced costs (the Redox uses Arduino Pro Micro instead of the Teensy 2.0).
  • Either half can be plugged in to the PC since each half can act as the master.
  • Either half can work as a standalone keyboard to be used as a macropad/gaming keyboard.
  • RGB backlighting support.
  • 3D-printer friendly case.
  • Wireless
