Stepper Motor - 68 oz.in (400 steps/rev) - ROB-10846 - SparkFun Electronics I haven’t bought one yet but I was looking into this one. It is 400 steps per rev. I would probably do 10 stops per revolution (instead of 12) so that would be pausing every 40 steps. I was unaware of the need for a driver. Will you need a driver even if it is just 3V vs a 6-12V?
