Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Hi all,

I'm happy to share my latest "remixed" boards that are evolutions of an unsplit/unibody design that I originally released at the beginning of this year. These designs are heavily inspired by and borrow aspects from a number of other keyboard designs, including bad-wings by Hazel and revxlp by Pete Johanson.

The remixed designs use Kailh Choc switches with moderate spacing (i.e., not too close). These can have either 55 keys or 64 keys. For each of these sizes, I created a variant that uses a Xiao Seeed module and another variant that uses the Waveshare RP2040-zero module.

For me, it was important to have inverted T-clusters for navigation. These boards have two clusters, one of which has the arrow keys, and the other has Home/End/PgUp/PgDn. I also wanted to minimize the amount of pinky finger reach on the 64-key designs (since I have relatively short pinky fingers).

The RP2040 Zero has 20 pins on it and can fit some pretty large matrixes. It looks like they used a pair of shift registers on the XIAO build to get some extra column pins.
