Description

The EasyDriver – A3967 is a simple to use stepper motor driver that is compatible with anything that can output a digital 0 to 5V pulse. It has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. The EasyDriver can power wide range of stepper motor up to 30V.

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 and/or MS2 pin to ground to set the driver to use 1/8, 1/4 or 1/2 microstep mode (See the datasheet for the table of values). 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. The best part – low cost. The parts cost is easily less than $10, even less if you make the board yourself.

Features / Specifications
