Stepper motor through extension port


#1

I’m looking at creating a custom extension that requires an extra stepper motor. The extension port on the flux says it can control a stepper motor but the pinout doesn’t look like I can connect a stepper motor directly. Does anyone have any more information about adding a stepper motor through the extension port?

Ok looks like a need a stepper motor controller between it. Does anyone know the voltage of the signal pins on the extension port? I’m guessing 3.3v
