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.

Peel off the backing on the two acrylic pieces.

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

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

Insert the IMU board into the epoxy.

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

Epoxy the board onto the acrylic.

Let the epoxy cure for 4-6 hours.

On your ROV, remove the polypro fin.

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.

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

Clip the wires at that estimated length.

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

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

Use a heat gun to shrink the heatshrink around the soldered area of the wires.

Apply hot glue to the bottom of the IMU and place on the starboard side of the acrylic structure handle.

Make sure that the pressure sensor is facing down and the IMU is oriented towards the front of the ROV.

Updating the software will be required on most ROVs to get the IMU to work, even if you have the previous version of the IMU.

You need to be running software version 30.0.2 or later for it to function correctly. We recommend running the latest version.
