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
