Simple module for step and direction control of bipolar stepper motors.
Five different levels: full step, 1/2, 1/4, 1/8 and 1/16. Operating voltage between 8 and 35 volts. Power up to 1.2 amps.
With the adjustable current control, you can set the maximum current output with a potentiometer.
Intelligent chopping control that automatically selects the correct current decay mode (faster or slower decay mode).
Overtemperature shutdown, undervoltage shutdown and overcurrent protection Earth fault and short circuit protection.
