I2C, Multiple Shields, UNO

Projects General Guidance
1

I am working on a project where I need to use a motor shield, data logger shield, and LCD backpack (for an LCD). They are all Adafruit products. From what I can tell, they all use I2C (A4 and A5). Will there be an issue? I am pretty unfamiliar with I2C, but I read somewhere about addresses, and I know the motor shield (V2.3) has the option of soldering together pads in order to give it a different address. Do I need to give different addresses to all 3 shields?

Thanks

Generally, no. Motors and sensors start out with different addresses.

You would need to solder the pads if you had 3 motor shields and needed to give them different addresses.
