Peter Norberg Consulting, Inc. manufactures and sells controllers for operating unipolar and bipolar stepper motors.  These products incorporate easy wiring to the motors, and may be operated both by switch closures and though use of computer serial control (both USB and RS232).  They all support microstepping of the motors,  and can generate step requests at up to 62,500 microsteps/second (model dependent).

Our stepper motor controllers are designed to be useful to researchers, experimenters and hobbyists, and are appropriate for industrial applications. They are excellent for control of anything from small linear actuator devices to medium-duty X-Y positioning tables.  As-is, each can be directly used in small pan/tilt  mechanisms.  Using our products, only minimal external electronics are needed to operate any simple stepper-motor-driven device (such as implementing a computer-controlled security camera). 

Please see our product summary page for more details on these and other products.

Recent News and Announcements

February 15, 2008: Our new beta offering of the SimplexCNC application allows operation of small routers using a specialized firmware installed on our SD4DP four-motor step-and-direction controller.

November 1, 2007: We have released our SS0710USB upgrade to our SS0705USB dual unipolar motor controller product.  The SS0710USB doubles the current rating of the board to 1 amp/winding per motor, so more powerful motors may be used.  Please click here for more information.

October 19, 2007 (updated 29 October): We have released a preliminary beta version of our StepperBoard class library, rewritten completely using Microsoft Visual C# for the .NET 2.0 (and later) environments.  Please click here for more information.

July 23, 2007: We have released the  NCStepper4D firmware for the SS4D series of four motor controllers.  This firmware provides for synchronous operation of up to four motors from one board.

May 15, 2007: We have released our SS4Dxx USB four motor unipolar  controller. This extends our SSxx product line to include independent operation of up to four unipolar motors from one board.

May 15, 2007: We have released our SD4DP USB high performance four motor step-and-direction board!  This extends our SD4D product line to include on-board dual 8-bit DACS, and a higher motor stepping rate.
