1  Features 

The  TMC389  evaluation  board  features  a  TMC389  with  external  power  MOSFETs  plus  a 
microcontroller,  which  allows  interfacing  to  a  PC  for  visualization  and  control  of  all  parameters.  The 
motor can  be  operated  via  the  step  and  direction  interface, using  either  an  external  source,  or  using 
the integrated microcontroller as a step pulse generator. 
 

Highlights 

 

Evaluate all features of the TMC389 

 

Use stallGuard2

™ with your motor 

 

Use coolStep™ with your motor 

 

Control all parameters from a PC 

 

Motor current can be set to up 6A depending on sense resistor selection. 

 

Supply voltage up to 40V (MOSFETs can be exchanged against 60V 2A types) 

 

Access all pins of the TMC389 
 

Motor type 

 

3 phase Stepper
