I was hoping for them just on pieces of wire with heatshrink over the soldering like the white and self flashing ones I have already got off ebay. That is prettymuch specific to a pushbutton on a board like that.
I guess it depends on the application. If you want to stuff them in a joystick or something like that, then the RGB Drive boards obviously won't work. But others have used them for more than just pushbuttons.
The issue with RGB LED's is that 3 resistors and 4 wires are required for each LED, so parts and labor make for an expensive combo. You can't reduce parts to keep costs down, so one has to reduce labor. This is usually done by using a small PCB, similar to the one used with the RGB Drive.
Other configurations will probably be at least double in cost. But if you need a decent quantity and don't mind paying for the work, feel free to shoot me an email.
