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:

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.

This discrete MOSFET stepper motor driver enables control of one bipolar stepper motor. It supports a wide 8 V to 50 V operating voltage range and can deliver up to 4 A continuous per phase without a heat sink or forced air flow (6 A max with sufficient additional cooling). The SPI interface allows configuration of the current limiting, step mode (9 step modes from full-step through 1/256-step), decay mode, and stall detection. The driver also provides back-EMF feedback that can be used for more advanced control and stall detection algorithms. Additional features include reverse-voltage, under-voltage, and over-current protection.

This breakout board makes it easy to use Toshiba’s TB67S128FTG microstepping bipolar stepper motor driver, which features adjustable current limiting and microstepping down to 1/128-step. In addition, it has the ability to dynamically select an optimal decay mode by monitoring the actual motor current, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power consumption and heat generation. The driver has a wide operating voltage range of 6.5 V to 44 V and can deliver approximately 2.1 A per phase continuously without a heat sink or forced air flow (up to 5 A peak). It features built-in protection against under-voltage, over-current, and over-temperature conditions; our carrier board also adds reverse-voltage protection (up to 40 V).

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).

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.
