    The motor required a lower current (150 mA) than conventional stepper motors (1A), and it was possible to drive the motor by the output pins of Arduino (40 mA, 5 V). The standalone micro-stepper motor (without the gearbox) has a step angle of 18° (π/10 rad). With the gear ratio of 300:1, each angular step was decreased to π/3000 rad.
