The Stepstick and Pololu motor drivers are the heart of just about every Reprap electronics board, but they can go bad. The usual way of testing these things is to rig up a microcontroller on a ...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

The project illustrates a unipolar stepper motor driver that is able to handle 20A current. When driving a stepper motor, the voltage provides the speed while the current provides the torque. For the ...

The R525 microstepping step-motor driver measures just over 3.3 inches long and 1.3 inches high, making it easy to accommodate in most systems. It’s capable of outputting a 5-A peak current and ...

Allegro MicroSystems, LLC introduced a new, flexible microstepping motor driver with a built in translator for easy operation. Allegro’s A4992 is a single chip solution designed to operate bipolar ...
