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.


Features:
Simple step and direction control interface
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Short to ground and shorted-load protection

Much smaller than I thought it would be

My mistake I did not look closely at the size and had thought it would have a much larger foot print. I have yet to use the item but can see no reason that it will not work as it is week designed and assembled. Certainly worth a punt at the prince
