Hello.

We at Pololu are excited to announce the release of the Dual MC33926 Motor Driver Shield for Arduino, an easy way to control two brushed DC motors with an Arduino or Arduino clone.  The shield operates from 5 to 28 V and can deliver a continuous 3 A per motor.  Our Arduino library simplifies interfacing with the shield by providing methods for setting the motor speed and direction, reading the motor current, and checking for motor faults.



This shield is a lower-power, lower-cost alternative to our original Dual VNH5019 Motor Driver Shield, and it offers most of the same features along with a very similar interface.  For more information, including links to the shield library and user's guide, please see the dual MC33926 motor driver shield product page.  Please don't hesitate to ask if you have any questions, and we welcome your feedback!

Great product  :)
How do I control 3 motors with current-sense feedback with a single Arduino ? :~

Using one two-motor shield? Hardly seems likely, does it?

Yeah, I understand that you can't run three motors on a dual motor Pololu shield thats obvious.
Is there a method to stack 2 shields on the UNO and only use one motor driver on the top dual motor shield ?
My concern is that the motor output pins line up on the two shields and the third motor is just run in parallel with the bottom shield and therefore I will have no seperate control of the third motor.
Maybe this is not the forum to ask and I should post on the Pololu site  :smiley-roll:

It's a valid concern, because that is exactly what will happen. You'll either need a shield designed to drive three motors, or you'll need to mount the second shield to a breadboard, and connect the motor pins to other pins on the Arduino.
