Perfect. Thanks and yes, although my little TP241MC01G can't take 5V, i'm sure YOUR OLED isn't transparent ( ͡° ͜ʖ ͡°) I think i'm going to design the schematic on page 8 as a PCB on Eagle (or more likely Fritzing as I my heart really isn't in mastering Eagle) to save my mind when trying to wire up that on a breadboard. As always, many thanks.
