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
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)
Supply voltage can interface directly with 3.3V and 5V systems; 45V maximum
Built-in regulator (no external logic voltage supply needed)
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
Short-to-ground and shorted load protection
4-layer, 2 oz copper PCB for improved heat dissipation
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 drivers
