Step 1 — IMU/Depth Module 1.0 for OpenROV v2.7 (Stopped production June 2015)

First set up wires accordingly to the IMU, refer to image 1. Red/gray to 3.3v, black/gray to GND,green/gray to SCL, and white/gray to SDA.

Have the wires go through the top of the board and solder on the bottom side.

Clip the excess wires.

Wear safety glasses when clipping excess wires.

Step 2

Peel off the backing on the two acrylic pieces shown in image 1.

With gloves, acrylic cement the thicker piece on top of the thinner piece.




Step 3

Start the epoxy process by applying some to the bottom surface. This will ensure there is no airtrapped under the electronics board.

Insert the IMU board into the epoxy.

Step 4

With a piece of tape, tape down the wires to the acrylic piece as show in image 2.

Keep wires coming out of the board straight or the final piece won't be able to fit.

Make sure the entire board is flush to the acrylic.




Step 5

Epoxy the board onto the acrylic.

Cover the board but DO NOT cover the white sensor. Refer to image 2.

Let the epoxy cure for 4-6 hours.

Step 6

On your ROV, remove the polypro fin.

Also remove one side of both of your threaded rods.




Step 7

Pull out the IMU wires from your ROV. Should be tucked on the starboard side of your wire bundle.

Cut off the heat shrink, and strip the wires.

Step 8

Once the epoxy has cured on the IMU, thread the wires through the third piece of acrylic. Refer toimage 1.

Acrylic cement the pieces together. Refer to image 2.




Step 9

Measure out the IMU wires to the stripped wires on the ROV from the starboard side of the acrylicstructure. Refer to image 1.

Make sure that the wires will not get in the way of the spinning propeller.

Clip the wires at that estimated length.




Step 10

Clip 4 pieces of heat shrink and place on the IMU wires.

Step 11

Solder on the IMU wires to the ROV wires. Make sure the wires you are soldering together matchin color.

After you have soldered all 4, slide the heat shrink over the solder joints and use the heat gun onthem. Ensure it is completely sealed by heating it till glue protrudes from the ends.




Step 12

Apply super glue to the bottom of the IMU and place on the starboard side of the acrylic structurehandle.
