Hi,
The schematic I found for the RUMBA board here, does not match the pinout detailed in pins_RUMBA.h from Marlin 1.1.8
Some pins does not match for instance LCD-D4, LCD-D7, ...

Does anyone know where to find a correct schematic for the Rumba ?

I am trying to install TMC2130 stepper driver , and look for where to connect CS pins ..

My fault . Rumba Schematic is correct and pin number ok. Marlin firmware use arduino pinout, the RUMBA schematic does schow only 2560 pin names.
