  • What is the reasoning behind connecting SDA/SCL to A4/A5? This shield does not work with my arduino (Metro M4 Express) without making any modifications to it!

    • That's where SDA and SCL are located on the Uno, eventually we will move the IC2 pins over to the R3 layout locations on the other side of the board when this product gets revised.
