TMC5160 StepStick V1.2 Motion Controller

Bedmonds91

Hello, I need to drive the TMC5160 Stepstick V1.2 as a motion controller mode, ie SD mode needs to be pulled low. I can't find the schematic anywhere and I can tell that the jumper on the board only switches the SPI mode on and off.

Bedmonds91 hello,do you fine the schematic? I also need the schematic to choose SPI mode

Hello, I ended up buying a TMC5161 StepStick and was able to get the SPI mode working by pulling the SD_PIN low. However, for my application I would like to use the single wire UART interface but only DIAG0 is available, which is for the SWN (negative) data line. The data sheet says you need SWP (DIAG1) at least for the single wire UART communication. It would be really helpful to get a schematic of this PCB to see if I can connect to the correct pins.
