A4988 driver board widely used un… printers and small Computer Numerical Control machines
Simple step and direction control interface
Thermal protection, over-current protection, ground fault protection
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Adjustable current control lets you sine temporethe maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage toachieve higher step rates
