Abstract – This work presents a open loop stepper 
motor driving, with configurable parameters, such as 
driving schema and nominal current. The developed 
system is based on microcontroller, monolithic switches 
and discrete analog electronics, aiming to reduce the 
overall cost. The building blocks employed on the system 
are briefly presented and are divided in: Digital 
Electronics, Analog Electronics and Power Electronics.
Experimental results with the assembled system 
suggested the well behavior of current regulation for 
various driving schemas, such as half step and micro step
