  • The A4988 stepper motor driver carrier is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 – 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

    • 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
    • Comes complete with self adhesive heat sink.
