TMC2130 Silent Step Stick RAMPS Adapter PCB

To be able to connect the SPI lines for TMC2130 stepper drivers on a RAMPS board I designed the attached PCB. It allows direct connection of all SPI lines point to point instead of requiring a single point to connect to multiple points on the stepper drivers (eg for SPI CLK, MOSI and MISO). It also allows to keep using a REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER LCD screen sharing the same SPI interface of the microcontroller (arduino).

Since PCBs can be ordered for about 5 euros includin
