"Regulated Current" Products. 

We currently sell three lines of regulated current products.  The UCC30xx series of controller boards are complete Unipolar dual-axis stepper motor controller systems, the BC2D15 controller board is a complete Bipolar dual-axis stepper motor controller system, and the BC4D15 controller board allows for control of up to 4 bipolar motors.

All of the controllers include the capability of driving one or two stepper motors at high speeds using current control techniques; the main differences between the product lines have to do with the types of motors controlled (Bipolar or Unipolar), and the single-winding current which can be attained..

These units are a good choice for those designing products which require higher motor speeds, since they can easily "over-voltage" the motor (to attain the higher speed) without overloading it.

The following table summarizes the currently released product key capabilities.  Please click on the product name for more information.

Firmware for the BC2D15 Motor Controller

The BC2DPotStepper firmware allows you to control two motors independently of each other, optionally using a potentiometer to control the rate of motor motion.  Please click here for a complete manual describing this offering.

The BC2DPotRouter firmware is similar to the BC2DPotStepper firmware, but adds the capability of 'routing' serial commands to a child board in a 'daisy-chain' arrangement.  Please click here for a complete manual describing this offering.

The BC2DNCStepper firmware  permits our stepper boards to operate two motors in a tightly coupled environment, appropriate for Numerical Control machines (such as X-Y tables).  Please click here for the complete manual describing this feature.

Firmware for the BC4D15 Motor Controller

The BC4DPotRouter firmware allows you to control four motors independently of each other, optionally using a potentiometer to control the rate of motor motion.  It also permits daisy-chaining of controllers, so that large numbers of motors may be operated using just one serial connection.  Please click here for a complete manual describing this offering.

On September 19, 2005, we released the beta version of our NCStepper firmware for the BC4D15 product line.  This firmware allows control of 4 stepper motors in a 'linked' fashion, as is appropriate for Numerically Controlled operations.  Please click here for more information....
