For example, we can connect even a 2.5A rated stepper motor, but we will limit the current of the driver to 1.5A.
With this we can easily set how much current the motor will draw no matter the motor rating. It is recommended to keep the current to around 1A, but of course, it is also possible to go up to 2A of good cooling is provided to the IC.Ī great feature the A4988 stepper driver has, actually all other drives have, is the current limiting. The A4988 has a maximum current rating of 2A per coil, but that’s actually a peak rating. You can watch the following video or read the written tutorial below which also includes all example codes and wiring diagrams. So, we got quite a lot to cover in this tutorial. Also, I will show you how we can easily control multiple stepper motors using an Arduino CNC shield for any type of Arduino project.

I will explain in details how they work, how to connect stepper motors with Arduino, how to set the current limit of the drivers and how to program them with or without an Arduino library. I have already used it myself in many of my Arduino projects, like the following: This combination of stepper motors and drivers is used in countless applications where position control is needed, such as 3D Printers, CNC Machines, Robotics, Automation machines and so on. We will cover how to control a NEMA17 stepper motor in combination with a A4988, a DRV8825 and a TMC2208 stepper driver. In this tutorial we will learn everything we need to know about controlling stepper motors with Arduino.
