Micro-stepping Stepper Motor Driver Board – Allegro A3967

Description

The EasyDriver stepper motor driver lets you control a stepper motor with a whole new level of precision. The EasyDriver uses micro-stepping to move the motor fractions of a whole step. It can make 1, 1/2, 1/4, or 1/8 steps, increasing the step count of your motor by a factor of 8. This is accomplished with the use of PWMs. The EasyDriver can run a stepper motor at voltages from 6-30V and it can vary the coil current between 150-700mA.
