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.

This version of our A4988 Stepper Motor Driver Carrier ships with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Please see the A4988 Stepper Motor Driver Carrier product page for more information about the driver.

This is a bulk-packaged version of our A4988 Stepper Motor Driver Carrier that ships without header pins. Please see that product’s page for more information about the driver. This version requires a minimum order quantity of five units and is intended for customers interested in higher volumes at lower unit costs. We will manufacture these to order and generally expect orders of up to a few hundred units to ship within a few days.
