From the project

Hardware design, BOM, gerbers and 3D files for Basic-stepper-driver designed by Soldered Electronics.

This driver for stepper motor enables control over a stepper motor that does not require more than 800mA of current and works at up to 14V voltage. Except for the driver, it has built-in LED lights that indicate which phase of the motor is currently active. Connecting with microcontroller is easy, and control is directly through the library.

This repository contains all design files for Basic stepper driver, organized as follows:
