Now add the GPS shield to the top plate. Remove the adhesive backing, and stick the shield
to the inside of the top shell around the GPS module so that it is completely covered and the
cables are arranged as neatly as possible.
Lastly, you’ll connect the components from the top shell to Pixhawk and reattached the top
shell.
Connect the two cables from the GPS: connect the six-wire cable to the GPS port and the
four-wire cable to the I2C splitter.
Connect the buzzer cable to the BUZZER port and the safety button to the SWITCH port.
Connect the red-white-and-black three-wire cable to Pixhawk’s RC IN pins with the black wire
connected to ground ( - ), the red wire connected to power ( + ), and the white wire connected
to signal ( s ).
If you haven’t performed the Pixhawk Adjustment Improvement Update on your IRIS, we
recommend completing this process before attaching the top shell. For instructions, select
Pixhawk Adjustment under Improvement Updates at 3dr.com/iris/info.
Place the top shell over the plate, ensuring not to pinch any of the wires. Hold the shells
together, turn IRIS over, and secure the shell using the remaining screws. Don’t forget the
screw inside the battery compartment.
