It is very useful to have the schematics for the Silent2209; I am using v3.1. I now need to remove R8 to operate with the half-duplex UART on my MPU. Both the MPU and the TMC2209 expect the line to stay high during turn-arounds while R8 is pulling it low. I am pretty sure, using a DMM which resistor this is but there is no ident info on the PCB, is there a layout drawing available which identifies all the components? There are other resistors or links I may need to add or remove for optimal performance in the future.
