Stepper Motor Drivers

Stepper motor drivers are specifically designed to drive stepper motors, which are capable of continuous rotation with precise position control, even without a feedback system. Our stepper motor drivers offer adjustable current control and multiple step resolutions, and they feature built-in translators that allow a stepper motor to be controlled with simple step and direction inputs. These modules are generally basic carrier boards for a variety of stepper motor driver ICs that offer low-level interfaces like inputs for directly initiating each step. An external microcontroller is typically required for generating these low-level signals.

Most of our stepper motor drivers are available in compact (0.6″×0.8″), pin-compatible form factors. The following table compares our selection of these:

Please note that this category also includes several larger driver modules, such as the AMIS-30543 carrier, that are not listed in the above table.

For higher-level control of a stepper motor, consider our Tic Stepper Motor Controllers, which feature some of the same stepper motor driver ICs as our carrier boards combined with an on-board microcontroller that intelligently generates the low-level control signal in response to a variety of interfaces, such as USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, analog voltages for use with a potentiometer or analog joystick, and quadrature encoder for use with a rotary encoder dial. The Tics also offer a wide array of settings that can be configured over USB through a free software utility.

These breakout boards for STMicro’s STSPINx20 bipolar stepper motor drivers feature eight different microstepping resolutions down to 1/256-step, adjustable current limiting, and a wide operating range of 7 V to 45 V.

These breakout boards for Toshiba’s TB67S2x9FTG bipolar stepper motor drivers feature adjustable current limiting, adaptive gain control technology, seven microstep resolutions (down to 1/32-step), and more. They operate from 10 V to 47 V and can deliver approximately 1.2 A or 1.7 A phase without a heat sink (depending on the version).

These breakout boards for the MPS MP6500 bipolar stepper motor driver feature adjustable current limiting, over-current and over-temperature protection, and four microstep resolutions (down to 1/8-step). They operate from 4.5 V to 35 V and can deliver approximately 1.5 A per phase without a heat sink (driver is rated for up to 2.5 A per coil).

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).

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 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).

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.

This breakout board for TI’s DRV8880 microstepping bipolar stepper motor driver features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/16-step). In addition, the driver’s current limit can be dynamically reduced to save power, and it has an autotune feature that automatically selects the decay mode that results in the smoothest current waveform. The carrier 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 DRV8880 operates from 6.5 V to 45 V and can deliver up to approximately 1 A per phase continuously without a heat sink or forced air flow (up to 1.6 A peak). This board ships with 0.1″ male header pins included but not soldered in.
