5V 64-step 4-phase Stepper motor with ULN2003 interface board specifically for interfacing with Arduino based projects.
A, B, C, D four-phase LED indicates the status of the stepper motor work
Dimensions of Board : 31 × 35mm
ULN2003 Darlington using high-power stepper motor driver chip


  • The rotation angle of the motor is proportional to the input pulse.
  • The motor has full torque at standstill(if the windings are energized)
  • Precise positioning and repeatability of movement since good stepper motors have an accuracy of – 5% of a step and this error is non cumulative from one step to the next.
  • Excellent response to starting/stopping/reversing.
  • Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
  • The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
  • It is possible to achieve very low speed synchronous rotation with a load that is directly coupled to the shaft.
  • A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
