About the Tmc2209 devboard PCB

Tmc2209 devboard is an open source PCB design by Neumi, published on GitHub. It is a 2-layer board measuring 69 × 53.8 mm, with 35 components from 22 distinct parts.

Other key parts include the TMC2209-LA. By type, the board carries 12 resistors, 8 capacitors, 5 connectors, 5 jumpers, 3 diodes and 1 IC.

It belongs with the robotics & motion and dev boards & breakouts designs in this gallery.

From the project

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

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
