All links are examples, I recommend looking around for better orders, and especially switches that you like
1: The following components can be omitted, if you don't want RGB: SK6812 MINI-E, 1xAO3401A, 2N7002, 2x10k resistor, 1x560R resistor
2: These are for power delivery (only!) between the halves, so you can charge them at the same time, but they are technically optional
3: Optional, if you don't need an encoder
4: You might find these as "XIAO NRF52840" or similar. There is also a sense variant which is more expensive and not necessary
5: Optional, if you don't need a display

Questions
How big is the Dodo keyboard PCB?
It measures 161.9 × 120.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dodo keyboard use?
116 parts, built around the XIAO NRF52840, SK6812MINI-E and AO3401A. 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 Dodo keyboard KiCad files?
From the gorbit99/dodo-keyboard repository on GitHub, at the commit this page was made from: the board is DodoKeyboard.kicad_pcb and its schematic DodoKeyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dodo keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask gorbit99 before reusing the design.
