Product description
Stepper motor with driver board based on the very popular ULN2003A motor driver. The board can be connected directly to a microcontroller and controls the stepper motor by sending alternating pulses to the motor coils. The LEDs on the board indicate which phases/outputs are active. The motor has an internal gear reduction of approximately 64:1.
