Hello, I have recently been looking into the Arduino MKR Zero for a project.
It fulfills all of my requirements (microSD, I2C, JST LiPo Connector, ...) except I can't find the I2C logic voltage. I know the board runs on 3.3 V, and the pins are all 3.3V, however I am confused by the additional I2C connector which has a 5V rail.
Does this mean I2C is also running on 5V? Can the rail be set to 3.3V for 3.3V sensors?
