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 62,500 microsteps/second (step rates are board model and firmware 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
On
June 20, 2009 we released our updated
USBToTTL converter boards.
Both now have ESD protection, while one (the USBToTTLEU) now
supports providing a 5 volt tap from the USB bus (which
automatically shuts off if the computer goes to sleep).
We also released our updated UCC30xx series of current regulated dual axis unipolar controller boards. The new versions are USB based, have ESD protection, and support optional powering of the logic portion of the board (NOT the motors!) off of the USB system.
On
June 5, 2009 we released our new SD4DGenIO firmware, which supports generic TTL I/O, encoder
operation, and pulse generation using the
SD4D series of boards.
On
May 29, 2009 we released our two upgrades to the
SD4D series of step-and-direction
controller boards. The SD4DEI
adds ESD protection and digital isolation, while the
SD4DEU adds ESD protection and
optional powering via the USB system.
On
March 10, 2009 we updated our StepperBoard class libraries (both the
Active-X and the .Net versions) to automatically keep the computer
from entering sleep as long as I/O is active to any of our stepper
controller products.
On
February 20, 2009 we released our
SimplexCNC application from beta testing. It is now
considered to be a fully released and supported product offering.
SimplexCNC allows operation of small
routers using a specialized firmware installed on our
SD4DP four-motor step-and-direction controller.
In August of 2008, we released an updated version of our popular
BS0710USB board (the BS0710USBHI) which adds ESD protection to most
of the TTL I/O lines, and which isolates the USB system from the
rest of the board. We also released an updated version of our SD4DP
four-motor step-and-direction controller, which adds ESD protection
to the TTL I/O lines.
