I am confuse on Minebea stepping motor pinout, is it the same with others unipolar stepper?
Verify my connection:
I am using ULN2003 to control
is it the 2 GND means com? can i supply voltage in them?
x,x!,y,y! works as GND?
:?

ULN2003 is not working to supply voltage to x,x!,y,y!~~

You need to connect common stepper motor to VCC, because ULN2003 only sinking current. So, the common need to + and current flow into the ULN2003.
You can refer this Stepper Motor Lesson.

So in Minebea unipolar datasheet stated 2 common is ground, right then i still can connect VCC supply it term of letting ULN2003 to sink current. Just wanna to confirm that in stepper motor depends on which way will supply either + or GND determine by current turn in the coil using right hand rule.

Thanks but the link couldn't open~~
