Jammie or Ted,
Could you clarify the following:
"its the same connections 1-14 3 does not need to be connected"
1) What happens to 15 and 16?
There are exactly the number of pins needed on that end. The other two pins are typically for backlight, which OLED doesn't use / need.
2) Is 3 the invertor?
OLED has no viewing angle adjust, therefore needs no angle POT for adjustment - that is what pin 3 is for.
3) do you need to solder each pin to the board?
In a rack, yes, in keyboard no. ON the display side, all pins get soldered.
"and you have to drill 4 holes"
1) How do you drill holes without compromising the tracks?
You may have to - I haven't had to do this, but in that case, you take kynar / wire-wrap wire and connect two points if it's necessary.
Many thanks.
Kevin
