Pololu DRV8834 Low-Voltage Stepper Motor Driver Carrier

This is a breakout board for TI’s DRV8834 micro-stepping bipolar stepper motor driver. It 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 micro-step resolutions (down to 1/32-step). This board ships with 0.1″ male header pins included but not soldered in.

This product is a carrier board or breakout board for TI’s DRV8834 low-voltage stepper motor driver; we, therefore, recommend careful reading of the DRV8834 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil. This product ships with all surface-mount components—including the DRV8834 driver IC—installed as shown in the product picture.

Note: For more technical data refer the attached datasheet

Features:

1. Simple step and direction control interface
2. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
3. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
4. 2.5-10.8 V supply voltage range
5. Built-in regulator (no external logic voltage supply needed)
6. Can interface directly with 3.3 V and 5 V systems
7. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
8. Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects.
