Stepper Motor Drivers

Subcategories

These breakout boards for Allegro’s A4988 bipolar stepper motor driver feature adjustable current limiting, over-current and over-temperature protection, and five microstep resolutions (down to 1/16-step). They operate from 8 V to 35 V and can deliver approximately 1 A per phase without a heat sink (they are rated for up to 2 A per coil).

These Black Edition driverse are higher-performance drop-in replacements for the original A4988 stepper motor driver carrier. They feature a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer version.

These breakout boards for TI’s DRV8825 bipolar stepper motor driver feature adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). They operate from 8.2 V to 45 V and can deliver approximately 1.5 A per phase without a heat sink (they are rated for up to 2.2 A per coil).

Pololu item #: 2131
Price: $7.49

This is a breakout board for TI’s DRV8824 microstepping bipolar stepper motor driver, a lower-current version of the DRV8825. It can deliver up to 0.75 A per coil without a heat sink (it is rated for up to 1.2 A per coil with sufficient additional cooling), and it has larger current-sense resistors than the DRV8825 that allow for improved microstepping performance at low currents. This carrier has the same pinout, interface, and features as our DRV8825 carrier, which means it can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. This board ships with 0.1″ male header pins included but not soldered in.

This is a breakout board for TI’s DRV8834 microstepping 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 microstep resolutions (down to 1/32-step). This board ships with 0.1″ male header pins included but not soldered in.

Pololu item #: 1183
Price: $9.95
Quantity:

This is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver. It has two voltage regulators (5 V and 3.3 V), eliminating the need for separate logic and motor supplies. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 – 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling). This board ships with 0.1″ male header pins included but not soldered in.
