Re: Need A1708--820-00840-01 schematic with boardview
I do not get it. Why is everyone saying thanks to something that is wrong???? because the schematic that has been provided is for 820-00875 and NOT the 820-00840.
can't the mod's edit the thread title to ammend it?
For those coming to this thread, the post with the boardview is wrong. It is not a boardview in the sense we have come to know what boardviews are which are those which show the component identification and layout. The boardview in that post is actually a breakdown of the actual pcb and it's individual pcb layers showing all the pcb tracks and solder pads. It is therefore not what you think it is....
