Overview
Dodo67 is an open-source printed circuit board by evyd13, from the evyd13/dodo67 repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 301.2 × 96.4 mm with 184 parts on 118 nets, routed with 1,180 tracks and 108 vias.
It is built around the ATMEGA32U4, USBLC6-2SC6 and WS2813B-B. Its parts include 88 switches, 71 diodes, 5 capacitors, 5 resistors and 2 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README
daughterboard/README.mdDodo67 Daughterboard
Same direction? Reverse direction...?
Please read this blog post: anykeys.eu/post/jst-cables...
In essence: the original Doro67 PCB needs a 'same direction' cable, while the Dodo67 PCB needs a 'reverse direction' cable. This is because the Unified Daughterboard specification uses the latter.
HOWEVER, the first version of the Dodo67 PCB, which was sold by MyKeyboard, uses a reverse direction cable.
What's the hole for?
The hole next to the breakout pins (which you can solder a wire to) is for cable relief! Use a zip tie to secure it to the daughterboard and prevent it from moving around.
A note on PCB thickness
This daughterboard is intended to be 2.0mm thick. This is so you don't need the washers like the original Dodo67 daughterboard did. You can use it in 1.6mm as well, but remember to use the washers in that case!

Questions
How big is the Dodo67 PCB?
It measures 301.2 × 96.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dodo67 use?
184 parts, built around the ATMEGA32U4, USBLC6-2SC6 and WS2813B-B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Dodo67 KiCad files?
From the evyd13/dodo67 repository on GitHub, at the commit this page was made from: the board is pcb/dodo67.kicad_pcb and its schematic daughterboard/daughterboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dodo67 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
