Features Simple step and direction control interface Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Can interface directly with 3.3 V and 5 V systems Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout Short-to-ground and shorted-load protection Exposed solderable ground pad below the driver IC on the bottom of the PCB Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information) 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) 45 V maximum supply voltage Built-in regulator
