This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. This diagrams was created using Fritzing software.
STEMMA I2C connector
You must change the jumper on the pads labeled "5V3" to the left of the connector. Cut the trace between "5" and "V" and bridge the "3" and "V" pads. See the pictures and text below. The SAMD51 does not like it if there are even light pullups to 5V and may hang on boot otherwise!
