## Description

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.   Get Started with the SparkFun ProDriver and Mini Stepper Motor Driver Hookup Guide 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.
