DRV8825 features an adjustable current limit  overcurrent and overheating protection  six micron resolution (down 1/32-step). the use 8.2-45 V  up to 1.5 per Arduino stage no heatsink or forced airflow (nominal to 2.2 per volume sufficient additional cooling).<br/><br/>Features:<br/><br/>1.?Simple steps and direction control interfaceStep<br/>2.
