FYI - Improperly Configured OLED

[AD2CS]

I purchased my kit from NewDIYTech and had a problem with the OLED not powering up. I tracked it down to the fact that jumper "2" on the OLED board was not closed. Jumper "3" was OK, and "1" and "4" were open as they should have been, but "2" was also open. Closed the jumper and all was well,,,
