This breakout board for the MPS MP6603 microstepping bipolar stepper motor driver offers microstepping down to 1/8-step and operates from 8 V to 55 V. It can deliver up to approximately 2 A per phase continuously without a heat sink or forced air flow (up to 4 A peak). The module has a pinout and interface that are very similar to that of our popular A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications. It features built-in protection against under-voltage, over-voltage, over-current, and over-temperature conditions, and configurable input modes allow it to alternatively drive brushed DC motors and other loads.
