Unipolar Stepper Motor Controller, 5V TTL, Up to 30V/3A Motors US$59.99

Unipolar Stepper Motor Controller, 5V TTL, Up to 30V/3A Motors

The Little Step-U is a complete stepper motor control solution in the form of a 1" 2" PCB. A single TTL serial connection is sufficient to control a 30V/3A unipolar motor up 5000 steps/second in a set-and-forget fashion.

Commands instruct the motor to move to an absolute position, to move to a relative position, to move until an input is activated, or to return to one of two previously marked positions. A built-in linear ramp function allows the motor to be accelerated and decelerated over a defined period.

Other options are to drive the motor in full, half and wave drive modes, to stop with windings on or off, or to act as a simple translator/drive with step and direction inputs.

Unipolar Stepper Motor Controller Features
