CozyKeys Bloomer

This repository contains the design files for the CozyKeys Bloomer, an 87-key ergonomic mechanical keyboard.

This keyboard has undergone several revisions and name changes. Previous names were Atreus87 and Ergo87 and artifacts of these may still be present in the repository.


Project Status


The first revision of the board was hand-wired and built as a proof of concept to ensure that the layout is comfortable.


The second revision added a PCB and a complete redesign of the case so that the PCB would fit accurately.

This initial PCB was functional but lacked any RGB support. It also had a few issues:

  • When placing the ItsyBitsy upside down to reduce the height needed between the switch plate and bottom plate, there is no easy way to access RST
  • Switch footprints were "flippable" which was misleading as the controller pinout only supported a single orientation


The second revision added several features and fixes:

  • Dedicated reset button with the case updated to make this accessible
  • Single orientation switch footprints
  • RGB underglow support
You can’t perform that action at this time.
