![]() The connections are also given in the table below. Wiring diagram for Arduino Motor Shield Rev3 with stepper motor. L298P, Drives 2 DC motors or 1 stepper motorĢA per channel or 4A max (with external power supply)įor more information you can check out the datasheets here. Arduino Motor Shield Rev3 Specifications Operating voltage I wrote tutorials for the A4988 and DRV8825 driver that work great with many stepper motors. ![]() If the motor you want to drive doesn’t work with this shield, I recommend using a chopper drive instead. I also found this stepper motor from Adafruit that works great at 12V and only draws 350mA. The motor I used for this tutorial draws around 1A at 5V. Since the shield can supply a maximum of 2 amperes per channel, you need to find a stepper motor that can be used in this voltage range and doesn’t exceed the maximum current rating. ![]() Not all stepper motors will work! The shield’s operating voltage is between 5 and 12 volts. 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.
