NAnoPi K2 linux GPIO layout?

Moderators: chensy, FATechsupport


I'd like to connect button LED ... to GPIO. I d'ont have the gpio unix name.
For example we can see it in the array for Neo board :
http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO2 ''linux GPio''
I dont see this information in :
Thus I don"t know how to use direct commands like :

echo "in" > /sys/class/gpio/gpioXXX/direction

Other solution : use the library :

But K2 seem not to be supported:

The question is simple : how to have gpio number/position information? I dont see it in schematic.

My initial aim is to use the power key button to halt K2 board without any display.

Thanks for your help
I had the same problem. Here is the pin layout I came up with:
