Subject: Re: [beagleboard] Re: Feature request: PoE
The dongle on adaifruit requires you to provide the 5volt dc power supply..
It's just a passive adapter..
but it got my thinking about the spagetti mess of 7 bbb's i have in the corner
for 24/7 testing. ;)
Regards,
Ah ok, yeah I did not realize it was only a power injector. I assumed it was
somehow stepping down 48VDC to 5V. So for your spaghetti mess, why not get, or
design a "power rail" like some do in data with many rack system, but instead
of 12, 5, and 3.3, just do 5 volts ;)

OK, so I'm not an EE, even though I do have a lot of experience with many form
of electronics, and definitely some with PoE too . . . But I'd think that it
should not be unheard of to get the price of a PoE cape down to under $20USD.
*That* would be useful to some I'm sure.

It was also the right decision... over the life of this forum, only 17 topics

I would imagine most people would rather not spend the extra cost of PoE if
they could avoid it. Even if somehow Gerald miraculously got the price down to
~$6 like the cost of that dongle you posted a link to Robert . . . Usually, PoE
items cost a lot more, which has me thinking that dongle is somehow suspect . .
