Pinout

View from the top side. Further infos can be also found in the schematics PDF file.

v1.x Pinout

TMC2130 v1 Pinout

Note: The SPI jumper is open by default and therefore the driver has to be configured via SPI.

v2.x Pinout

TMC2130 v2 Pinout

Note: The SPI jumper is open by default and therefore the driver has to be configured via SPI. The DCO pin is an output, keep attention that it is not connected to SDO, because some mainboards bridge these pins (also called SLP + RST).
