This A4988 Stepper Motor Driver Carrier is a breakout board for Allegro's easy-to-use A4988 microstepping bipolar stepper motor driver. The A4988 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A.

This board is fully assembled and ships with an aluminum heatsink.

Features:

  • 3.3 and 5 V compatible control logic
  • Operating voltage: 8V to 35V
  • Operating current: 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
  • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
  • Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
  • Short to ground and shorted-load protection
