Getting started with your new Atreus

You can find a guide to setting up your keyboard, installing Chrysalis, and updating the firmware on your keyboard, in the Keyboardio Atreus Getting Started guide

Keyboardio Atreus keyboards produced before June 2020 shipped with an early firmware version. While the firmware does work, its key layout is slightly out of date and there are a few bugs that may cause frustration while typing. We strongly encourage you to update your keyboard's firmware to the latest available version before you start typing on it.

Customizing the key layout

The easiest way to update your keyboard's layout is to use Chrysalis, our graphical configuration tool for Windows, macOS and Linux.

You can download Chrysalis at

Open source firmware

The Atreus is powered by Kaleidoscope, a comprehensive open source firmware for keyboards. Kaleidoscope is based on Arduino, so it's really easy to get started with.
