Stepper Motor Driver A4988
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.
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
