Nema17 stepper motor has higher torque and higher operating voltage than 28-BYJ48. In this tutorial, we are going to control NEMA17 stepper motor using Arduino Uno and A4988 stepper driver module. 28-BYJ48 has relatively lower torque than the other stepper motors like NEMA 14, NEMA17. In our previous project, we controlled 28-BYJ48 stepper motor using Arduino. Stepper motors provide accurate controlling, and can be differentiated on the basis of torque, steps per revolution, and input voltage. A stepper motor is a type of DC motor that works in discrete steps and used everywhere from a surveillance camera to sophisticated robots and machines.
