USB hub self powered to boat battery - davidbirnie - 05-23-2020

What do you people use to power another usb hub preferably on the boat battery so that the raspberry doesn’t get all the cables? Please links and some
expriences so I can find a good option.

There are a number of good post on powering the Rasp pi and the various other items that one might put to use for a build like an open plotter. Following this one here http://forum.openmarine.net/showthread.php?tid=2304 for example I purchased a Mean Well SD 25A-5 That I use to power the Pi itself and a GL-MiFi 4G Smart Router I am sure I can power a couple of other small items that will all be hard wired in the end versus running on the Pi's usb ports. I am sure if you search about though you can find other good examples of powered usb hubs or power converters like the example I used. Sill a work in progress but getting close to finished. I think if I had come into it early enough (and still having second thoughts) I might have gone down this route; http://forum.openmarine.net/showthread.php?tid=1807

Thanks for the reply. However I am not having a challenge powering my pi but to connect all the USB devices on the Pi and make sure they are all powered. So I was looking for a USB hub which I can power from 5v and attach with one cable to the Pi and provide me for example 4 ports. Any thoughts there?

Hi,
I have just started to use a D-Link DUB-H4 powered usb hub. Seems to work well so far. It is powered by one of theese: https://www.ebay.com/itm/DC-DC-Micro-USB...Sw02Fc0Ggu
The rpi itself is powered by another one.
Cheers,
