This breakout board for Allegro’s A4988 micro stepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different micro step 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.

The driver requires a logic supply voltage (3 – 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. 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)

Four, six, and eight-wire stepper motors can be driven by the A4988 if they are properly connected.
