TRINAMIC Motion Control's new TMC2660 stepper motor driver IC supports motor drive currents up to 4A. The new IC integrates both a pre-driver for real-time calculation of motor coil current values, ...

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.

Modern stepper motor drivers feature microstepping, a driving technique that squeezes arbitrary numbers of microsteps into every single full-step of a stepper motor, which noticeably reduces ...
