CozyKeys Speedo

This repository contains the design files for the CozyKeys Speedo keyboard. The Speedo is a 66-key ergonomic mechanical keyboard heavily inspired by the Atreus/Atreus62.

Speedo Front

Speedo Back

Features

  • Powered by an Elite-C microcontroller
  • Runs QMK firmware
  • Compact ergonomic layout
  • Supports underglow via 12 WS2812b RGB LEDs
  • Low profile (Switches mounted ~13mm from surface keyboard sits on)
  • Case/PCB design files free and open source

Build Guide

A build guide and parts list are provided at ./build_guide.md.

Details

Firmware

Release Notes

v3.0

After working on other keyboard projects for quite some time, I revisited the Speedo with a number of changes:

  • Removed the curved thumb key clusters
  • Changed the center key layout to add some more space between the left and right sides
  • Designed a PCB that uses the Elite-C microcontroller with support for 12 WS2812b RGB LEDs
  • Designed a new case to support the updated layout
  • Changed versioning scheme to make more sense

rev2

Speedo

The second version fixed the thumb clusters. I had yet to get into PCB design so this was only ever made via hand-wiring.

rev1

The first version of the keyboard didn't account for the diameter of standard keycaps and resulted in a case with faulty thumb
