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
