TMCM-1211 StepRocker

Stepper Motor Controller [&] Driver 5.7A/24V with USB/RS485/S[&]D

The TMCM-1211 StepRocker™ is a single axis motor controller/driver board for 2-phase bipolar stepper motors. It features the TRINAMIC motion controller/motor driver TMC5160 in combination with an ARM Cortex-M4™ (MK20DX128VLK7) processor. The Module is intended to be a fully functional development platform.

It is possible to use the StepRocker™ with the Trinamic Motion Control Language TMCL™. The board comes with the preinstalled firmware. The integrated development environment TMCL-IDE for PC can be downloaded and used free of charge. It is possible to remote control the stepRocker™ or to write and download complete command sequences for stand-alone use.

Alternatively for TMCM-1211 stepRocker an open source source code library TMCL LITE is available. Sourcecode can be accessed via GitHub.

For the first steps only a power supply, a stepper motor and a PC are necessary.
