StepperBoard Products

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 through use of computer serial control (both USB and RS232).  They all support microstepping of the motors, and some of the products can generate step requests at up to 500,000 microsteps/second (step rates are board model and firmware dependent: currently, the BC6D20 is by far our 'fastest' product).

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.

If you intend to order via the internet, we would suggest that you review our "Safe Internet Purchasing" page for some useful tips.  The most important warning on that page is to never send your credit card information (i.e., card number) via email or any unencrypted connection.
