Motor shield V2 stackable on other shield ?

by Iris90 on Wed Mar 10, 2021 5:55 pm

Hello,

I saw that it is possible to stack a shield on top of the Adafruit motor shield V2 if built with stacking headers. However, I have already another shield that connects to all of the pins of my Arduino UNO and I want to stack the motor shield on top of it. Would that work ?

Thanks in advance !

Yes. It should work.

The only possible issue is if your other shield has the same i2c address. If so, the motor shield address is configurable to avoid conflict. See the guide for details.

Thank you for the quick answer ! Yes I've already read about configuring the I2c address, it is quite straightforward.

Then, since the motor shield V1's I2c address is not configurable, stacking that one on another shield would not work (if both shields use the same address) ? I know that V1 kit is discontinued here, but there are some copies of it on the internet made by other makers so I am curious to know.

The V1 shield does not have an i2c address, so there is nothing to configure. It does not use the i2c bus at all, so there is no conflict with the V2 shield.
