Stacking Shields

I have a EtherTen Board and was wondering if I need to make any modification's to stack a H-Bridge motor shield then a 8 channel relay board on top of each other. Please forgive the newbie question but I couldn't find anything in the documentation and just wanted to be sure I didn't damage anything on the boards before proceeding.

Hi Andrew,

Yes, this is fine. You probably want to stack the HBridge (which has connections on top) on top of the relay driver (which has connections on the "wing" at the side).

The relay driver uses the i2c pins SDA/SCL, and the HBridge uses all digital pins. So there are no pin conflicts to worry about.
