2 Attach foam to Pixhawk.
Separate the four foam squares, and
remove the adhesive backing from
one side. Place one square onto each
corner of the bottom of Pixhawk
without disconnecting any of the
cables.
3 Align guide to plate.
Place the guide over the back-left
corner of the plate as shown. It may
be helpful to tape the guide in place.
4 Check position of splitter.
Align the top-right corner of Pixhawk
with the guide. If the I 2 C splitter is
touching Pixhawk, complete this step
to adjust its position.
Use a flat-head screwdriver or similar
tool to wedge the splitter and
adhesive gently away from the plate.
To avoid damaging the splitter, do not
use too much force or put pressure
on the connectors.
Move the splitter a few millimeters
away from Pixhawk so that it won’t
touch the board in its new position.
The splitter may overlap slightly onto
the cutout in the plate as long as it
can stick securely in place.

If the splitter touches Pixhawk in its new
position, use a tool to adjust the position of
the splitter so that it has a few millimeters
of clearance between the two components
as shown.
Be very careful when completing these steps! The adhesive on the foam will
only stick once, so make sure to place the pieces carefully the first time.
