Well, if you're going to be so snarky - have you read what I wrote? Did you even look at the graphic you linked to? There is clearly a Molex to wall-wart connector, which I said I do not want. :banghead:
I don't want wall-wart connectors. I want screw terminals than I can put stripped wires in. Stock, I have to de-solder the wall-wart connector and hard-solder in wires directly. I don't really want the Molex to wall-wart connector piece.
I will admit I'm an outlier more than a couple standard deviations from what most people want, and I really do *NOT* expect Andy to cater to my oddball tastes.

Why the hell do you need to desolder anything? :dunno
If you don't want to connect it to a PC molex then just cut the molex off and use a terminal strip.

I've been playing with the tlc5940s for a few days to create something similar and now it looks like I won't have to :) Great idea putting the flash on there.

Thats correct, the current is always 20mA. But connecting the LEDs in series would work.
It doesnt use TLC5940 by the way though...

I understand it, however, as the stock power connection is nearly impossible to reverse polarity. Maybe I'm just averse to wall-wart connectors.... :-[

Yes I thought most people would want to power from a PC power supply so we provide a cable which plugs into the PC power supply!
But some will use a mains adaptor (which we might sell at some time but are widely available) and this will plug into the connector on the board. I cant see how screw terminals can be better than this solution, you would need to cut off the connector on the mains adaptor and wire it to the screw terminals.

Thats a shame Andy. I wanted to wire four RGBs together and then run them off three outputs ( plus one 5v contact). I can wire them in parallel to achieve this but it sounds like that won't work with your board and I don't think you can wire standard 4 lead RGBs in series can you?
