Features:

➤Simple step and direction control interface
➤Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
➤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 to achieve higher step rates
➤Intelligent chopping control that automatically selects the correct current decay mode(fast decay or slow decay)
➤Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
➤Short-to-ground and shorted-load protection

Warning:

➤Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.(More generally, rewiring anything while it is powered is asking for trouble.)
