Regarding power through the Euler connector, how would you do that? Does that require a bench supply? Or is that using something like the DC-DC converter mentioned? Also, you mention only needing 2 pins, but could go to more. I assume 4 pins could flow more current? This may be a topic somewhere else already, so if it is, I apologize.
My goal to start with is use this thing for a media server, and I was going to plug in an external hard drive via the USB port. My concern is providing enough power that the hard drive could be powered as well. It doesn't have an option for external power, just gets it via USB, so that's why I'm so curious on this stuff.
Thanks again!
You could use a powered USB hub for your external hard drive.
You can attach to the pins on the Euler connector using DuPont cables/wires, using an appropriate 5 volt power supply. I'm using an old JAMMA arcade power supply as this not only provides 5 volts, but also features a potentiometer for adjusting the exact value of the 5 volt line. You could also theoretically power an external hard drive off this PSU, (either 12v or 5v HDD since a JAMMA PSU has both volatges).
This Power Pine64 via GPIO thread may be of some interest to you.
