Based on the same main PCB as the low profile build that I posted yesterday, this Ursula has an extra column, an extra row, MX switches, underglow and per key RGB LEDs, twin OLED displays, dual encoders on one side and a Pimoroni trackball on the other, and the SplitKB puck for tenting.
Are you processing the data from the trackball? Actually I should ask first which firmware you are using 🤔 My feeling with the trackball using kmk is not so positive.
It is no longer so difficult to set these up in QMK. The UX limitations of the Pimoroni trackball are a hardware problem, not a software problem.

That makes me happy to hear!
Also, from what dasky and others have said, defining MOUSE_EXTENDED_REPORT seems to help a good deal with the trackballs. (it changes the xy reporting axis from +/- 127, to +/- 32k).
Very nice!
Make sure you enable the extended mouse reports (#define MOUSE_EXTENDED_REPORT), as that seems to help with the pimoroni trackball!
How’s the experience been with the trackball?
Not great, admittedly. I'm working on another design that uses a Cirque trackpad, which makes for a better pointing device.
Have you seen all the improvements to the cirque code recently? can definitely recommend!
Great. I am going to try to set it up on a STM32F411 chip, which I think Mega pushed new Stemcell code for in the last week.
Finally a ergomech I can get behind. This might be the one for me!
Is this one on your GitHub too??
Yes. It is the same one posted in the other thread. https://github.com/jimmerricks/ursula.
I don't like the idea of having 2 knob's on the same side but maybe some people can find it useful, one for increase and decrease the volume and the other one for scrolling up and down 😅
That's the great thing about the Ursula. Don't like knobs, don't add knobs.
Really cool design. I find the outermost thumb key interesting - is that something you can reach? The thumbcluster and pinkie stagger is my biggest gripe about the sofle, this approach definitely looks more comfortable!
Reach, yes. Use, not really. I typically drive a 34 key.
Interesting, perhaps it's my hands that are weird 🙂
hot swap + wireless and let me buyyyyy
Thats sexy, not gonna lie!
oh man, if this were available to just purchase without assembly, I'd be so happy*.
*happiness dependent on availability in Europe, reasonableness of cost, and a million other factors that will never truly be fulfilled.
I'm in Europe. What would be a reasonable cost?
With switches and keycaps, maybe 250 Euro. Without maybe 170 I think.
That is more or less reasonable, I think. Maybe a little more when you factor in acrylic plates and labour costs. The tricky thing about being in Europe is the import taxes and handling fees when buying from multiple vendors.
