I am looking for BPi M1+ GPIO schema. Well I can find it on gitbooks or on banana-pi.org pages, BUT I can’t find from where the pins start (I might be blind) I mean I see that 1st 2 pins next to each other is: 3.3V and 5V, but how should I plug the cables to 1st 2 pins from the network/usb conectors OR from the end of the board?
