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, BC6D25 and SD6DX are by far our 'fastest' products).

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

On February 8, 2016, we released our BC6D25 2.5 amp/winding 6 axis controller This product is an upgrade to our BC6D20: it increases the per-motor-winding current maximum to 2.5 amps, and it sets the finest microstep resolution to 1/32 of a full step.

On January 24, 2016, we released our SD6DX 6 axis step-and-direction controller system. This product allows for operation of up to 6 external step-and-direction boards both as NC and asynchronous systems, to operate stepper motors and step-servos that our outside of the current capabilities of our other products.  It can generate step pulses at up to 500,000 pulses/second/motor.

As of January 2, 2016, our BC6D20 firmware has been udpated to support a scripting language that allows full access to its features.  This also provides the capability of optionally running the script as a standalone operation.

On June 1, 2015, we moved our web store to the "Shopify" system.  Our merchant pages now appear at

On September 8, 2014 we announced the full release of our BC6D20 6 motor controller system .  This product allows operation of up to 6 bipolar motors both as NC and asynchronous systems, at up to 500,000 microsteps per second per motor.

As of February 28, 2014, we now have RS232 versions of our popular BC2D20 BC2D20 with screw terminal connectors and BS1010 BS1010 with Amp MTA-100 connectors products available from our web store.
