ALLMOTION's STEPPER-STICK

The STEPPER-STICK is a full-featured Stepper Motor Controller + Drive built into a USB Stick. The Stick Measures 2 x 1 x 0.5 inch and can provide 0.25A of motor current if powered by the USB Bus or up to 0.5A if powered by an external power source. The controller performs fully profiled moves with control of acceleration, velocity and position. Additional rich features include quadrature encoder feedback, 4 Analog and Digital inputs, 2 On/Off power outputs, program storage, and a built-in logic sequencer that can loop, branch and control the stepper/outputs based on status of inputs. The STEPPER-STICK is designed for ultimate ease of use. Only a PC, a stepper motor and the STEPPER-STICK are required. The user needs to wire only four contacts for the stepper motor and plug the STEPPER-STICK into a PC. An engineer unfamiliar with Motion Control can have a stepper motor spinning intelligently in less than half an hour. The STEPPER-STICK is an introduction to the capability and programming language for a family of more conventional products at AllMotion. This family of products allows an engineer to progress to an OEM application with ease. Most designs with this functionality occupy about 10X the volume of this drive. Products of similar volume have only the "driver" and depend on the PC to perform the "controller" function. The STEPPER-STICK boosts the 5V from the PC to 15V and has a Bipolar Drive - similar products are typically Unipolar and 5V. The STEPPER-STICK has all intelligence built in, and once programmed can operate with no computer attached. In addition to Motion Control, the STEPPER-STICK has other capability such as Analog Inputs, Digital Inputs, and On/Off Power Driver Outputs useful in performing real world applications.
