Description
This breakout board for TI’s DRV8434 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 inputs for setting the decay mode and includes two smart tune current regulation modes that help you achieve smooth steps without manual tuning. 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.
