Stepper Motor Controller PWM Pulse Signal Generator Speed Regulator Board PWM Generator Stepper Motor Drives 15-160V / 5-12V by Amazon.co.uk

• Reasonable design--This module is supplied as a stepper drive signal. To control the stepper motor, but also must have the drive to use. Frequency of measurement can amount PUL and common cathode terminal (GND) two ports.

• Frequency--The controller has high, medium and low total of three types of frequency signals can be used to select jumper. High: 5.8KHZ-127KHZ, Mid: 590HZ-15.8KHZ, Low: 82HZ-2.3KHZ.

• PWM Generator--PUL + and PUL- pulsed positive and negative; EN + and EN- is to enable the positive and negative terminals; DIR + and DIR- are the positive and negative directions. These six lines are connected to drive the corresponding pulse, direction, so six ports possible.

• Power supply--15-160VDC or 5-12VDC. If you are using 5-12VDC power, positive end connect DC 5-12V Input, negative end connect Common Cathode End.

• Easy to use--The forward and reverse of the motor can be controlled by pressing the key. The speed of the motor can be controlled by adjusting the frequency of the potentiometer.
