Use a DRV8825 stepper motor driver with that motor. Use a power supply that can provide anywhere between 12v and 36v (higher is better) with an output of 2 amps (or more). Be sure to set the current limit on the stepper driver so as to protect the motor.Stepper motors are very inefficient and are not suited to battery power. If you must use a battery get a rechargeable one that can provide at least 12v and which has a capacity of at least 5 amp hours....RStepper Motor BasicsSimple Stepper Code
Hey I am using a A4988 as the driver, would it still be fine?
An A4988 will struggle to provide the 1.68 amps required by your motor. If it overloads it will cut out and you will miss steps. You could set it at 1.5 amps and maybe there would still be enough motor torque.A heat sink and cooling fan for the A4988 chip would help....R
it can hold up to 2 amps with it
Is that based on practical experience or just from reading the marketing blurb?...R
It's written on the datasheet
