Mapping Euler bus DC in and 5v DC out pins - g_t_j - 06-02-2016
Can anyone please -based on this image http://wiki.pine64.org/images/7/7d/Pine64_Board_Connector.png - map the exact pins used to power the board as well as those 2 that provide 5V?
Sorry if I've missed it but I couldn't find more info.

Please refer to Euler Bus on this PDF file: http://files.pine64.org/doc/Pine%20A64%20Schematic/Pine%20A64%20Pin%20Assignment%20160119.pdf
The DC in pins are the power in pin (+5V). the +5V pins are the +5V power pin. Somebody has post the photos on the forum.

Hi. The pin assignments for all interfaces on the Pine64 board are in a document on the wiki page. To save you some time, they can be downloaded here.
Edit: haha, TL Lim just beat me to it.

Τhanks very much both of you.
If you find that photo please post it here so that it'd be of some help to me as well as anyone else might be looking for this.

Find it, here is the photo link: http://linux-sunxi.org/File:Pine64_Powered_through_Euler_Connector.jpg
P/S: Thanks to Tkaiser

Amazing!
Thanks so much both of you guys!
I did finally locate the 2 pins providing 5V based on the diagram you provided and have successfully powered a 5V fan but was a bit reluctant to try anything on the Euler bus. There is no room for mistakes there as you can easily fry the board...
With that image, however, I'm on safe ground! I will make a USB-to-2 pin cable and will try to power the board!
Cheers!

Can anyone please let me know what is the maximum current that can be drawn from the 5v GPIO pins?
Please note, I'm powering the board through Euler bus so there's no 1.8A limitation.
As I'm trying to build a Hifi based on Pine64, I would also wanted to know how much current do the WiFi/BT module and LCD touch screen draw?
Finally, what is the maximum current I can provide to the board via the Euler Bus given that theoretically it is 1.8A via micro USB?

40mA according to A64 datasheet that can be access from Pine64 wiki site.
