I took the advice from a member which I won’t name.And I am building the usb charger from http://www.stefanv.com/electronics/usb_charger.html But I will replace the usb with a solar panel that has enough voltage and current of the same amount. I am having some difficulty trying to understand where to solder the backside because of the way the picture is flipped and laid out. And I tell yeah it is really confusing me.
Does anyone have any suggestions that could help in understanding where to solder everything correctly
