Summary
I am working on developing a RAMPS version that will allow TMC2130 drivers (using SPI) to be used, simply by moving some jumpers.
This is a link to a forums discussion about the board
The board is also meant to be usable with 32-bit processors that use 3V logic, like the Arduino DUE

Design files
As soon as I know that the design actually works, all files I have/use will be made available.
