Pixhawk I2C/Power Connection: The four-wire connector enables I2C communication to Pixhawk, and also powers the sensor. Connectors are available on the web-store. Check the diagram below for proper wiring.
Mounting Orientation: The sensor should be mounted in a particular orientation with respect to the Pixhawk flight controller. For example, see the IRIS+ images to the right. The sensor should face straight down (i.e., toward the ground).
