Ethernet power supply standard
Which Ethernet standard has the Up squared power circuit implemented? When I look at the specifications page and even search for common phrases like IEEE 802.3af, IEEE 802.3at, poe, and power over ethernet all searches conclude with no results.
If it's impossible to power the device using common standards, please at least indicate this and offer an alternative. There is no USB-C port, so I assume some header is used as a 3,7V or 5V intake? I've searched for such information as well and only found that no battery connector exists and a JST-PH header serves to supply power to connected peripherals. It seems there is no schematic to help with such research either.
This is really confusing! Is it possible that the only way to power the Up squared computer is through use of a large and nonportable external AC/DC converter plugged into the barrel connector? Are any of the 3V3 or 5V connectors listed on the specifications page intakes or do they all simply supply connected devices?
Please list at least three ways that the Up squared computer can be powered, and recommend the best method to power in a mobile configuration.
I can create a USB-C integrated hat board if needed, but prefer to not reverse engineer the DC-in hat to find the information. I don't even think the DC-in hat authors have bothered to publish the schematics, either.
