John Riggles published his DELPHI, an "ergolinear" low-pro orthoish split.

Would you like to contribute to this year's MK Advent Calendar? Here are the guidelines for authors, along with last year's edition for reference.
DELPHI stands for "Dual Ergolinear Low-Profile Human Interface", and this board by John Riggles (aka JRiggles) is a minimal split designed to combine ergonomics and an ortholinear layout into a small form factor.
I first posted about this project a couple years back, and I've finally gotten back around to it. I'm still tweaking the design a bit to accommodate some PCB plates I had made, and I'm also working on a 3D-printable case – JRiggles.
This "ergolinear" layout has an orthoish grid, but is also columnar due to the exactly 1U pinky stagger.
Specs
- 40-42 keys
- Low-pro Choc switches
- Adafruit QT Py RP2040 controllers
- Thumb cluster supports a 3×1U or a 1×1U + 1×2U layout
- KMK firmware
