1  Features 

The  TMC262  evaluation  board  features  a  TMC262  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 both, using an external source, and using 
the integrated microcontroller as a step generator. 
 

Highlights 

 

Evaluate all features of the TMC262 

 

Use stallGuard2™ with your motor 

 

Use coolStep™ with your motor 

 

Control all parameters from a PC using special software or TMCL-PC 

 

Motor  current  can  be  set  to  up  to  1A,  2A  or  up  to  4A  (soldering  jumper)  via  on-board  sense 
resistors 

 

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

 

Access all pins of the TMC262 
 

Motor type 

 

2 phase Stepper
