EasyDriver 4.4 (Stepper Motor Driver)

EasyDriver 4.4 (Stepper Motor Driver)

LE 95.00

This is the famous bi-polar stepper motor driver called easydriver. It has microstepping capability.

Each EasyDriver can drive up to about 750mA per phase of a bi-polar stepper motor. It defaults to 8 step microstepping mode. (So if your motor is 200 full steps per revolution, you would get 1600 steps/rev using EasyDriver.)

This setting can be easily overridden by tying the MS1 or MS2 pin to ground. It is a chopper microstepping driver based on the Allegro A3967 driver chip. For the complete specs of the design, read the A3967 datasheet.

It has a variable max current from about 150mA/phase to 750mA/phase. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V regulation, so only one supply is necessary.
