A4988 DRIVERS
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 over-temperature protection, and five different micro-step resolutions (down
to 1/16-step). It operates from 8~35V and can deliver up to approximately 1A per phase
without a heat sink or forced air flow (it is rated for 2A per coil with sufficient additional
cooling).
