A4988 Driver Module StepStick Stepper Motor Driver For Reprap 3D Printer


SKU: 000037 Categories: , Tag:


Simple step and direction control interface

Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-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)

Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection

Short-to-ground and shorted-load protection

Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
