TMCM-078 Single axis stepper driver 7A/75V (step/dir.)

Description
The TMCM-078 is a single axis step/direction stepper motor driver that can be operated with supply voltages of up to 75V and up to 7A RMS (9.8A peak) motor coil currents. All major parameters can be set via DIP switches (no PC necessary for set-up) and up to 256 micro-steps are supported for either high accuracy or high speed. The system features sensorless stall detection (stallGuard™) and the module is fully protected, also coming with a stand-alone reference search feature.
