STEPPERSTICK Stepper Control+Driver

Stepper Motor Controls

The StepperStick was designed to allow a first time user to learn to move a stepper motor intelligently in under half an hour.

Housed in a USB Stick measuring only 2" x 1" x 0.5” thick, the fully intelligent stepper motor Controller + Driver is capable of moving bipolar stepper motors of 0.5A current.

A Bipolar Stepper motor is wired to the stick via 4 wires. When inserted to the USB of PC, the drive draws power up to 0.5A from the PC, which is adequate to drive a small motor. The StepperStick appears as a Virtual Com Port, and commands are easily sent via ASCII text from any serial terminal program (such as HyperTerminal) or from the EZStepper Windows application.

The Commands are intuitive and simple. For example, the command A10000 will move the stepper motor to Absolute position 10000. (This communications protocol is compatible with devices that use the Cavro DT or OEM protocol.)

The StepperStick is also capable of stand-alone operation with no connection to a PC. It can be set to execute a preset string of commands upon power up (i.e., only power is required in this mode). The Commands include nested loops and execution halt pending a switch closure, which is useful in stand-alone applications.

The StepperStick Stepper Motor Controller + Driver will work with any stepper motor that is 1.7" or smaller (size17 or smaller). This drive is designed to enable a first time user to make a Stepper Motor move intelligently in less than half an hour.
