Stepper motor drivers convert pulse signals from the controller into motor motion to achieve precise positioning, adjustable current control and multiple step resolutions, works great for 3d printer extruder and cnc machinery

Key Features:

* Anti-Resonance provides optimal torque and nulls mid-range instability
* Motor auto-identification and parameter auto-configuration when power on, offer optimal responses with different motors
* Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
* Soft-start with no “jump” when power on
* Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
* Automatic idle-current reduction
* Suitable for 2-phase and 4-phase motors
* Support PUL/DIR mode
* Over-voltage and over-current protections
