Provide power in via Pi-2 header

There is a jumper (J9) to bypass the MT3608 power regulator, but only in the Pine A64+ 2GB version, at least in the Rev C. So yes, it's possible in A64+ 2GB Rev C (maybe also in previous revs), but it's not possible in any other version, at least for the moment.

So are you suggesting that back power via the Pi-2 interface is possible if you remove both jumpers?  I have the board you are pointing out.  My jumpers are, according to the manual, jumped to DC 5V setting.  With the board jumpered as shown the MT3608 over heats and the board shuts down if you provide power input via the Pi-2.  Power input via the Euler DC IN pins works just fine.
