SparkFun Mini Stepper Motor Driver - TC78H670FTG
The SparkFun Mini Stepper Motor Driver empowers you to control bipolar stepper motors with ease and precision. This compact driver, measuring just 0.6in. by 0.8in. with breadboard-friendly 0.1in. pin spacing, shines in space-constrained projects and prototyping applications. Getting started is a breeze thanks to our comprehensive Arduino Library, which boasts 10 examples to guide you through the process. Furthermore, you achieve unmatched control over your motor's movement with high-resolution capabilities down to 1/128th of a step.
The Mini Stepper Motor Driver offers two control methods for greater flexibility: traditional clock-in stepping and serial commands. The serial control method unlocks unique features, allowing you to fine-tune your motor's performance on the fly. Adjust phase, torque, current limit, and mixed decay ratio easily through user-friendly serial commands. Unlike most stepper motor driver ICs that require an external trimpot for current limit adjustments, the Mini Stepper Motor Driver empowers you with software-based control, eliminating the need for physical adjustments.
Note: For a tool-less version of this motor driver, please check out our ProDriver. However, it should be noted that there is a slight difference in the functionality of the
3V3 pin. The ProDriver only requires a single input power supply, as the 3V3 pin is a voltage output.- Toshiba TC78H670FTG Bipolar Stepping Motor Driver

So this would be able to drive a stepper motor like the ROB-10846? Since its 1.7A/phase?
Yes, it can drive this motor. However, you would not be able to drive the motor in such a way to utilize its maximum torque. So it depends on your application. For your reference, it is rated for 2A max, so that effectively means 1A per phase. It is a matter of how much torque you need for your project and therefore how hard you want to drive it (it will heat up as you approach 2A).
