Hi ehrack,
I already writing a User Manual / Datasheet for SOPine, but it's not ready yet. By looking SOPine, Baseboard schematics and A64 and AXP803 datasheet, you will find many useful information (mainly, look the AXP803 datasheet for powering).
As far as I researched, there is two ways of powering the SOPine:
- by DCIN pin, (check for ranges in AXP803, but verified is 5V), this pin is for directly powering the Power Management Unit, also for charging battery if preset
- by VBUS pin, powering from li-polymer or li-ion batteries
Just choose one, and the device should power up. (Please, verify everything with datasheets, I can't promise that I written upper is right, but it should be ).
Also, I did some tables with GPIOs and Pin Assignment, it may be useful for you:

If you will have any other questions, come to Pine64 IRC or Discord, and ping me => gamiee
