I hope you enjoyed taking a look at a smarter-than-usual stepper motor driver, as one of the new frontiers of DIY 3D printing, and as an interesting component with many other applications.

ST has released a new evaluation board for a stepper motor driver. It’ll plug right into your 3D printer, and if you’re looking for a chip to build a cheap 3D printer controller board a… ...

Multifunction printers, for example, often use a three-phase BLDC-motor driver or a stepper-motor driver (either one channel or two channel) for the paper mover.
