Upgrade Kit Instructions Thank you for purchasing an IRIS+ Upgrade Kit. You’re now ready to transform your IRIS into an IRIS+. You will need: -Phillips-head screwdriver -2 mm hex key -Glue for foam, preferably hot glue but Gorilla Glue or RC modeling adhesive will also work. -Small, flat, prying tool for removing DF13 connectors. You will reuse the screws and cables from your original IRIS, so don’t lose them during disassembly. IRIS+ Upgrade Kit Instructions vB | ©3D Robotics, Inc.
1 Disassemble Remove the screws in the bottom shell and inside the battery compartment. For more specific instructions on removing the replacing the shells, visit 3dr.com/iris/info. In the next step, you’ll temporarily disconnect some of the cables connecting to Pixhawk: DF13 connectors are difficult to remove without damaging the ports. Use the prying tool to lift the edges of the connector gently away from the port.
Remove the four screws holding each arm in place. Turn IRIS over, and remove the bottom shell. You should be able to pull the arms partially away from the body of IRIS. Now you’ll need to disconnect the two plates by tearing the foam. Try to separate the foam from the plate with the ESC as cleanly as possible at the surface of that plate so there is minimal foam attached to the smaller plate. Once the smaller, bottom plate is detached from the foam.
2 Reassemble with IRIS+ parts Now you’ll switch to reassembling IRIS with the parts from the Upgrade Kit, starting with the preconnected arms, motors, legs, and ESC. First, disconnect the red-and-black six-wire cable from the old ESC, and connect to the same port on the new ESC. Before you attach the ESC to the bottom shell, you’ll need to arrange the cables so they will be situated properly to connect to Pixhawk. Locate the gimbal cable: red, brown, and yellow three wire with split connectors.
Now you’ll connect the arms to the bottom shell and bottom plate using the longer screws. Align the two holes in each arm with the holes in the plate and shell, and insert the screws from outside the bottom shell. Be careful not to damage the external USB module and plate it carefully above the plate. This image shows the correct orientation of the cables after attaching the arms. (LED cable not pictured.
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.
3 Update Parameter File and Add Stickers to Controller 2 Select Config/Tuning 1 Connect to Mission Planner Connect the telemetry radio to your laptop, power IRIS, select the COM port, set the rate to 57600, and select Connect. 5 Select Write Params to save the new parameters. The parameter loading process is now complete. 4 Select IRIS+ Select the drop-down menu to view available parameter files, and select 3DR_Iris+.param.
4 Add Propellers and Tall Legs Propellers IRIS uses four propellers: two with black nuts and two with silver nuts. Attach the propellers with black nuts to the motors with black tops and the propellers with silver nuts to the motors with silver tops. Tall legs Switch to tall legs to use IRIS with the Tarot Gimbal or for extra clearance on landing. Use the small (1.5 mm) hex key to loosen the set screw in the bottom of the leg. Each propeller has locking and unlocking direction symbols.
