Rather than having the host Pi communicate directly with the stepper drivers, the 3+Pi features an onboard STM32F302CBT6 that handles the actual motor control.

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

He was able to get it running with an Arduino in no time so he decided to take the project a little bit further. What he ended up with is a stepper motor driver which can be controlled over Bluetooth.

Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control ...

Even first-time users can get a stepper motor moving as commanded in 30 min or less. Commands can be issued from any serial terminal program or from the EZ Stepper Windows program, but the EZHR17EN ...

If a motor driver was ever made for Arduino and battery power Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 ...

The αSTEP AZ Series stepper motor driver offers superior high speed open loop performance with closed loop control. It incorporates a battery-free, absolute mechanical encoder for absolute-type ...
