MRIYA VS cantor

All the models I use are available in the lib folder

There are a few things that are close: * The Cantor/Piantor: more aggressive stagger and slightly changed thumb cluster. * The Swept Corne: essentially a big sweep. * The Hillside 46/48: This comes in many forms which are very similar to what you are looking for. Essentially an extra aggressive stagger (and perhaps splayed) Corne with a bigger thumb cluster.

Depending on how comfortable you are ordering PCBs yourself, the Cantor (https://github.com/diepala/cantor ) or the Cheapino (https://github.com/tompi/cheapino ) might be a good starting point for getting into split keyboards, both are diodeless, so you only need to solder the switches and use relatively cheap microcontrollers

The Corne caught my eye first, but I ended up starting with a Cantor, which has more stagger, like OP's keyboard. It didn't work for me. The Corne works better for me.

Cantor by DiePala, Choc, diodeless, cheap “Black pill” mcu, requires two. Caseless/plateless. Pcb is reversible, but you’ll need trrs cable and Jack.

I have 2 hand-wired keyboards with cherry style switches, and I decided to build a Cantor (diodeless, Corne-like with more pinky stagger) to try a PCB build and the Kailh choc v1 switches for a first time.

several of the low-profile / Choc boards (ex. Cantor) go the plateless and caseless route with nothing more than rubber bumpers on the bottom of the PCB
