Provide power in via Pi-2 header
#21
Thanks for that Marcus.

And to address the questions that ciclopez and BenCranston raised earlier which I missed (my apologies!), ciclopez was correct, I had neglected to mention in my earlier statement that this was on a Pine64+ 2GB board (RevB in my case), which has the jumper for DC/BAT power.

However, as I indicated in my earlier post from June '16, and can be seen from the schematic, when the jumper is in the DC position, the 5v bus(es) are coupled directly to the DC_IN pin, and the pine64 can be powered from the 5v pins RPi header. So if you have a hat which powers your Raspberry Pi, as long as you have a pine64 board with a power select header, it will power your pine64. Nothing should overheat. The pine64 runs perfectly stable, drawing approximately 215ma @ 5v when idling with a HDMI connection active.

So that should hopefully end that confusion. The Pine64 512MB board does not have the jumpers, and thus can only be externally powered via the DC_IN on the euler bus. The Pine64+ 2GB board has the jumpers, and can be powered via the rPi header once the jumper is in the DC(_IN) position. As always, it is not recommended that you power via the headers (regardless of which header you connect to). MicroUSB is the safest option unless you know what you're doing! Wink

@marcus: Do you know if the Pine64+ 1GB board has the DC/BAT jumpers on it? The schematic does NOT show it, and pictures of the RevB pine64+ 1GB do not show the jumper present. Unless there was a RevC which added it, the pine64 store page needs to be updated as it shows a board with the jumpers.
