Topic: Using official Motor Shield with Arduino Uno (Read 601 times) previous topic - next topic


I have a new Arduino Motor Shield and an older Arduino Uno.

My Uno does not have all of the same pins as the shield. The Motor shield has pins for IOREF and SCL and SDA that are not present on my old Arduino UNO. I know that the new Arduino R3 does have these pins.

How can I use this shield with this Uno? Is it OK to cut the extra pins off of the motor shield? What would be the consequences?

From the schematic, these pins are just pass through, they allow stacking another shield that would use these pins.

So yes you can cut them if needed to fit the shield, the motor driver chip itself doesn't use them.
