It would be great to see the Dimple supported!
There have been many runs of this 40% keyboard, as well as a few similar boards that use this layout.
It differs from the 40% kit, in that it has a second 1.25 on R3. (As well as a second 1.75u on r4, but that is already present in the base kit!)
All you'd need to do is add that one key as a configurable option.
Thank you!
