Support for Alternative Layouts
This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

There will be a bunch of debug pin changes in the shipping version (only adding, not removing any). Due to some initial power supply issues with the internal regulator we'll be moving to an external 3.3 V regulator. I'll also add a debug for this as well which could be useful to supply 3.3 V peripherals.
The LCD was easily powered by the internal regulator, but it just made more sense to run everything off of a single regulator with a higher max output (1A instead of 130 mA). For example, some backlit keyboards use anywhere from 400-500 mA @ 5 V so I think the external regulator is a good idea in this case.
(Would require either not fun pcb rework or a board respin to use the internal regulator)
Also, would the required rework interface with the case?
