Open the USB Ethernet adapter carefully

Remove the board from the housing

I used a TRENDnet TU-ET100, but most simmilar 'gumstick' adapters should work

We need 5V power for the Topside Adapter. The best place to get them on this board is on the underside.

Before you solder, check which pins are Ground and +5V

According to USB standards, Ground should be Black and +5V should be Red (the wires with these colors are on the other side)

Use some small gauge wires and solder them onto the pins carefully

Make sure you don't short two pins.

There are normally 4 wires + 1 for the shielding

The wires you connected on the USB-Ethernet board need to be connected to the Topside Interface Board

The best spot for +5 is the solder point of J5 that is closer to the Mini USB port (red)

The best spot for GND is the GND pin of J4.

Be careful to find the right solder points

Get/make a short ethernet cable like the ones that connect the Homeplug adapter and the BeagleBone in the ROV and connect the two boards

You should be ready to test the setup by plugin in the USB cable to a USB port on your computer

You should see a new network card showing up in you operating system

The green Power LED should light up on the Topside Interface board

You will need to cut a new housing for the slightly bigger electronics

When assembling make sure you route the USB cable out at the bottom (red marker) before you glue the parts

Well done!
