Description

This breakout board for TI’s DRV8434A microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and operates from 4.5 V to 48 V. It can deliver up to approximately 1.2 A continuous per phase without a heat sink or forced air flow (2 A peak). The driver has integrated stall detection and uses a ripple control algorithm that allows tight regulation of current level and increased motor efficiency. 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-current, and over-temperature conditions.
