What this means for you, is that you need to be careful when selecting the stepper motor and power supply to use with this shield. This means that the current draw depends on the relationship between the inductance and resistance (L/R) of the motor that you connect to it. One thing that is very important to remember is that the L298 is a constant voltage driver. It comes with two separate channels, called A and B, that you can use to drive 2 DC motors, or 1 stepper motor when combined. With the shield, you can drive DC motors, a stepper motor, relays, and solenoids. The Arduino Motor Shield Rev3 is built around the L298 dual full-bridge driver, made by STMicroelectronics.

This one from Adafruit works great at 12 V and doesn’t draw too much current (350 mA). Try to find a stepper motor that can run at 5-12 V and doesn’t exceed the 2 A current limit. In this tutorial I used a bipolar stepper motor with 4 wires.

Actually, there are two separate Arduino codes. What’s left for this video is to take a look at the Arduino code. I also included 12V, 5V and GND connection pins, as well as pins for selecting the stepping resolution of the drivers. For those Arduno pins which I didn’t use, I included pin header connections so that they are available in case we want to use them for something in future. I used both the top and the bottom layer for running the connections. This PCB will actually act as an Arduino MEGA shield because we will be able to directly connect it on top of the Arduino Mega board. Nevertheless, in order to keep the electronics components organized and get rid of the wiring mess, I designed a custom PCB using the EasyEDA free online circuit design software.
