A4988 Stepper Motor Driver Carrier
This breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 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). This board ships with 0.1″ male header pins included but not soldered in.
Alternatives available with variations in these parameter(s): header pins soldered? bulk packaged? Select variant…

Arduino library for A4988, DRV8825, DRV8834, DRV8880
This Arduino library, written by forum member laurb9, allows users to control a stepper motor with our A4988, DRV8825, or DRV8834 carriers. The library has functions that enable users to set rotational rate, change microstepping mode, and specify how many steps to take or specify how many degrees to rotate.
