USB Outlets (Vimar)

[PMC]

I just finished a project adding several USB outlets around the boat. I had a few requirements

• Clean look, keep to factory appearance
• Fast charging (2 amp)
• Run on 12v battery power

I was searching around and found that my outlets and switches are VIMAR IDEA. The system is very modular, and they make USB (part number: VM16368). Many of the switches are 3 gang trim plates, with a blank, giving room to add in a USB connector.

The Vimar connectors are non powered, and need to be wired. I picked up a bunch of 5 volt DC / DC converter that runs on 12 volts. I used 2 types

• 3 amp output, for a single connector
• 5 amp when supplying 2

After a lot of reading and testing, I found what it takes to charge both the iPhone and Samsung android devices in 2 amp mode. I ended up with a 10k & 33k ohm resistor configuration on the data terminals. This is the same on the 2 amp fast chargers.


Here is the finished product (sorry for the rotation, uploaded from a tablet)

Nice work Paul. Looks great.

I added a couple of USB ports as well. One on 12v side and so far one on 110v side. I will take some pictures and post them later.

FeLiz Do you have specific pictures you are looking for? The first post has all the Finished and In-Process pics (do you see them?)

Sorry. I did forget. I will try to remember tonight.


Did not get out to the boat to take pictures yet, but here is the charging port I added to the helm: It is a Blue Sea Systems Dual USB Charging Port I got on Amazon. http://www.amazon.com/Blue-Sea-Syst...&redirect=true&ref_=oh_aui_detailpage_o06_s00

Ok. Here are some pictures:

I picked up the outlets with the USB ports at Home Depot.

Paul,
Any chance you can post a clearer picture of your schematic?
Thanks!

I posted a new (clear) schematic pic on the first thread

Why are you putting voltage (~1.2V) on the data pins?

Thanks Paul.

It is replicated my (Samsung) fast charger. It applies 1.2v on the D+ D- pins. I measured several 2 amp chargers, and they are all doing the same.
