Features:

*Maximum output current is 2A

*Simple step and direction control interface

*Five-step resolution:full,half,four,eight,and sixteen steps

*Adjustable current control allows you to set the maximum current output using a potentiometer

Enables you to use a higher voltage than the stepper motor's rated voltage to achieve higher step rates

*Intelligent chopper control automatically selects the correct current decay mode(fast decay or slow decay)

*Over-temperature shutdown,under-voltage lockout and cross-current protection

*Short circuit to ground short circuit protection
