The A4988 stepper motor driver carrier is a breakout board for Allegro’s easy-to-use A4988 microstepping bipolar stepper motor driver and is a drop-in replacement for the A4983 stepper motor driver carrier. The driver features adjustable current limiting, overcurrent protection, and five different microstep resolutions. It operates from 8 – 35 V and can deliver up to 2 A per coil.Here are some of the driver’s key features:

1. Simple step and direction control interface
2. Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
3. 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)
4. Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
5. Short-to-ground and shorted-load protection
