Moreover i'm looking for a driver like astroberry focuser with which to control a stepper motor using the bcm pins of the odroid, do you know any driver like this?
thanks again
Did you check the driver development page?
I was able to develop my own driver driving Orion AccuFocus from a RPI GPIO pins with a motor breakout board
It's not a stepper but I think you can do it the similar way.
