Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) . A4988 driver board widely used in 3D printers and small CNC machines. Simple step and direction control interface. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage toachieve higher step rates. Thermal protection, over-current protection, ground fault protection.
