Leveraging the Trinamic TMC2208 stepper motor driver gives Ethersweep silky smooth and quiet motor control, which could be very important for some applications.

The EZHR17EN can microstep up to 1/256 steps, while the daughtercard can microstep up to 1/16 steps. Even first-time users can get a stepper motor moving as commanded in 30 min or less.
