[4] Connect Sensor to Copter & 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.


Sensor-to-Pixhawk Pin Connections

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). It is important that the sensor is mounted level with Pixhawk.

An IRIS+ Sensor bracket is available in the web-store.
