TMC2130 RAMPS/Re-ARM Adapter PCB
thingiverse
I upgraded my AM8's electronics stack from an Arduino Mega to a Re-ARM a while back. The Re-ARM doesn't connect anything to several of the AUX2 pins, so the usual approach to run TMC2130s is to commandeer the pins for the Ethernet interface and use them for software SPI. This adapter board makes running TMC2130s on a RAMPS/Re-ARM stack simpler to wire. The original board design was done in DipTrace. I first converted it to EAGLE format, then imported that into KiCad. The result of that conversion is in the master branch in this project's Git repo: https://gitlab.com/salfter/DisplayTMCAdapter/ Select the rearm branch to get this remix. Since Thingiverse doesn't know about zipfiles, remove ".thing" from the end of DisplayTMCAdapter.zip.thing to get to the KiCad files and gerbers.
