-
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
-
Get the laser cut files here: https://github.com/OpenROV/openrov-contr...
-
When assembling make sure you route the USB cable out at the bottom (red marker) before you glue the parts
What program was used to do the laser cutting schemes? Solidworks? Autocad?
Hey Nils,
I used Corel Draw for the laser cutting files and exported to DXF. For simple structures as this box is, that's very easy. - Dominik
