What is this?
This is a special operation control module for single-axis stepper motors. The module has built-in multiple fixed operation modes, and users can quickly select the appropriate motion trajectory. It can save and set the distance/speed/delay/number of cycles after power failure.

What will I get?
DC Motor Controller
Shell material:Plastic
Universal voltage:DC 5-30V
Color:Gray
Model:ZK-SMC02
Size:79mmx43mmx41mm/3.11 inchx1.69 inchx1.61 inch(L*W*H)
In the package of:1pcs x Speed Adjustable Stepper

Are there any advantages of the product?
The motor speed controller is made of good circuit board materials, with good durability and wear resistance, which can ensure long-term use. The motor controller has a soft start protection function, which can effectively reduce the inrush current, protect the motor and extend the life of the motor. The digital encoder knob can adjust the motor speed, which can control the engine speed more accurately and consistently than ordinary potentiometers. With a wide range of applications, you can use this adjustable motor controller in different occasions and for different purposes.

How to use it?
1.Connect a DC power supply (5-30V) to the "+" and "-" terminals.
2.Link your motor's wires to the output terminals (A+/A- or B+/B-).
3.Use the potentiometer or external signal to set desired RPM.
4.Power on and fine-tune using the status LED for feedback.

What should I notice?
1.Need to be used with a stepper motor driver to control the stepper motor. 2.The product is not designed for life-saving, life-sustaining purposes, and cannot be used in some places such as coal mine and oil warehouse.
