Description

An Arduino shield to test the TMC2209 stepper motion controller by Trinamic.

README

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!
