DRV8834 Low-Voltage Stepper Motor Driver Carrier

The DRV8834 stepper motor driver carrier is a breakout board for TI’s DRV8834 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications. The DRV8834 operates from 2.5–10.8 V, allowing stepper motors to be powered with voltages that are too low for other drivers, and can deliver up to approximately 1.5 A per phase continuously without a heat sink or forced air flow (up to 2 A peak). It features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step).
