Power Pine64 via GPIO

[TeaPack]

So, can anyone tell me the max Vin for this board?

The power requirements are clearly written: 5V/2A. If you want to destroy the board feel free to inject higher voltages (5.1V maybe even 5.2V are fine, especially when powering through Micro USB since voltage drops will occur anyway)

Regarding test points please have a look at the schematic (no idea whether this has been released or not)

Well, PMIC on this board can work with max of 7V and unfortunately, microUSB is connected directly to Eulers pins, so there is danger of destroying other devices connected to microUSB port, when Pine is powered over pins...

Keep in mind that schematic is not valid as it relates to power on the 2Gb model, there were changes and that revised schematic has not been posted.

Just because the PMIC has a tolerance of 7v doesnt mean they designed the board so that anything else sharing its Vcc rail can handle that. Why, I bet there are capacitors on the board rated for 16v.....

Also according to that schematic D+ and D- on microusb are not connected, so, what would you hook to it other than power?

Personally nothing =) but if someone tests more options and forget to unplug the cable, something can get hurt... =) and I was checking schematics for 20 minutes to figure out if DCIN on Euler and USB lines are connected to anything else and I couldn't find anything.

Hope new schematics will be released as soon as possible...
