I am planning to use a motor sheild (link given below) to control a stepper motor and an Ethernet sheild for my Arduino uno. I would like to know if i can use both the shields on the same arduino board on top of each other. What can i do if the pins used by the motor shield is also used by the Ethernet shield? will this be a problem? Please help


Link for the motor shield -

In principle it’s possible to stack shields, but it heavily depends on the shields and the things you’re going to do with them.

If both shields need permanent access to the same pins, you can not stack them. If they use the same pins, but not at the same time or if they never use the same pins, it should work.

Hope this helps!

Thanks Maik. That was helpful :). I am just going to try it and see what is happening. hopefully it works, i will post the results.

And don’t forget about the capacitance. If the capacitive load gets too high it might even kill your outputs !

Happy making, Stephan
