Additionally, we now offer a 4 motor controller, summarized below.

SS4DxxUSB Unit

The SS4Dxx USB Four Motor Unipolar Controller Board is our four motor upgrade to the SS0705USB board (below).  It allows for inexpensive control of up to four (up to 1 Amp/winding) 4-pole unipolar stepper motors.  This tool is great for control of most small unipolar motors, and for the home robotics experimenter!  Please click here for the details...

 

BiStep2A 2 Amp Unit

The BiStep2A provides support for operating two 2-amp motors, or one 4-amp motor (using the GenStepper firmware double current mode); thus allowing for a much larger set of motors to be controlled by the system.

 

  BiStep A06

The BiStepA06 Controller Board allows for control of up to two simultaneous unipolar or bipolar stepper motors, at up to 1 amp per winding (2 amps per motor) and up to 35 volts. In Double Current mode, a single 2 amp motor may be run!  Please click here for the details...

 

  BS0710USB

The BS0710USB Controller Board allows for control of up to two simultaneous unipolar or bipolar stepper motors, at up to 1 amp per winding (2 amps per motor) and up to 35 volts. In Double Current mode, a single 2 amp motor may be run!  Please click here for the details...

 

 

SS0705 Unipolar

The SS0705 Unipolar Controller Board allows for inexpensive control of up to two small (up to 0.5 Amp/winding) 4-pole unipolar stepper motors.  This tool is great for control of most small unipolar motors, and for the home robotics experimenter!  Please click here for the details...

 

SS0705USB Unipolar

The SS0705USB Unipolar Controller Board is our upgrade to the SS0705 board (above).  It allows for inexpensive control of up to two small (up to 0.5 Amp/winding) 4-pole unipolar stepper motors.  This tool is great for control of most small unipolar motors, and for the home robotics experimenter!  Please click here for the details...

 

SS0710USB Unipolar

The SS0710USB Unipolar Controller Board is our next upgrade to the SS0705USB board (above).  Twice as powerful as the SS0705 series, it allows for inexpensive control of up to two 1 Amp/winding 4-pole unipolar stepper motors.  This tool is great for control of most small unipolar motors, and for the home robotics experimenter!  Please click here for the details...

 

SS0905USB Unipolar

The SS0905USB Unipolar Controller Board is an example of one of our specialized versions of the SS0705USB board (above).  It allows for inexpensive control of up to two small (up to 0.5 Amp/winding) 4-pole unipolar stepper motors.  This tool is great for control of most small unipolar motors, and for the home robotics experimenter!  Please click here for the details...

 

  SimStep Unipolar

Our original SimStep Unipolar Controller Board allows for inexpensive control of up to two small (up to 0.5 Amp/winding) 4-pole unipolar stepper motors.  This tool is great for the home robotics experimenter!  Please click here for the details...

 

  Sockets and Shrouds

The "Sockets and Shrouds" kit provides crimp-based shrouds and sockets for the SimStepA04 and BiStepA04 boards as they are currently shipped. Please click here for the details...

 

Common Firmware Options of the SimStep and BiStep series of Motor Controller Boards

The GenStepper Firmware (our most popular firmware) allows you to control two motors independently of each other.  It also supports a "double current mode", wherein a single motor may be operated at up to twice the rated current of the board!  Please click here for more information about this product.

The NCStepper 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 more information on this new feature.

The PotStepper Firmware  allows you to control two motors independently of each other.  The rate of motion of the motors may be controlled via a user-provided potentiometer.  As with the GenStepper firmware, It also supports a "double current mode", wherein a single motor may be operated at up to twice the rated current of the board!  Please click here for more information on this new feature.

RelayStepper Firmware  permits our boards to simultaneously operate one motor and up to 4 relays, as well as providing for up to 9 TTL input signals.  Please click here for more information on this product.

The SerRoute Firmware can operate any number of stepper motors via one serial line!  This firmware option allows for 3 (default configuration) to 9 (optional) motor controller boards to be operated via one serial port,  if it is installed on a SimStep series unit, thus providing for 6 to 18 motors controlled by one 9600 baud connection using just one SerRoute-based board as the serial supervisor.  If multiple SerRoute based boards are used as routers, there is no upper limit to the number of motors which can be controlled by one line.   Please click here for more information on this product.
