TMC2209 Development Board for Arduino Uno

A development board to test the Trinamic TMC2209 stepper motor controller on an Arduino Uno.

This board should cover all options and IOs that Trinamic provides for its TMC2209.

Facts:

All TMC2209 pins are connected to digital pins of the Arduino.
XT30 power connector
voltage source selector Arduino VIN or XT30
TVS diodes on 5v and 28V lane of the TMC2209
different wiring schemes for the JST motor connector (because getting the right phases is not easy apparently!)
different current setting selectable with solder bridges (or custom resistor also possible)
motor voltage sensing via voltage divider on A0
reset button for Arudino + power LED

KICAD and production files for JLCPCB are also included. Code will follow. Production cost incl assembly is around 50€ for 5pcs. THT components not included.

Feedback is very welcome!
