Warning: This carrier board uses low-ESR ceramic capacitors, which makes it susceptible to destructive LC voltage spikes, especially when using power leads longer than a few inches. These supplies should have appropriate decoupling capacitors close to the board, and they should be capable of delivering the expected currents (peaks up to 4 A for the motor supply). The driver requires a logic supply voltage (3 V to 5.5 V) to be connected across the VDD and GND pins and a motor supply voltage (8 – 35 V) to be connected across VMOT and GND. Minimal wiring diagram for connecting a microcontroller to an A4988 stepper motor driver carrier (full-step mode). (A version of this board with headers already installed is also available.)

You can also solder your motor leads and other connections directly to the board.

The headers can be soldered in for use with solderless breadboards or 0.1" female connectors. The A4988 stepper motor driver carrier comes with one 1×16-pin breakaway 0.1" male header. Unipolar motors with five leads cannot be used with this driver. For more information, please see the frequently asked questions. those with six or eight leads) can be controlled by this driver as bipolar stepper motors. We also have a variety of other stepper motor driver options in this same form factor with different operating profiles and features. For customers interested in higher volumes at lower unit costs, we offer a bulk-packaged version without header pins and a bulk-packaged version with header pins installed. This product ships individually packaged with 0.1″ male header pins included but not soldered in we also carry a version with male header pins already soldered in. This product ships with all surface-mount components-including the A4988 driver IC-installed as shown in the product picture.

Short-to-ground and shorted-load protection.

Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.

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.

Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.Simple step and direction control interface.Here are some of the driver’s key features: This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil (see the Power Dissipation Considerations section below for more information). This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection we therefore recommend careful reading of the A4988 datasheet (1MB pdf) before using this product. A4983/A4988 stepper motor driver carrier with dimensions.
