I have several of those mini-controllers you mention and their rated power dissipation of 144 watts is not quite achievable; they run very warm, almost hot, when running a single RGB strip 16 feet long. And that's only about 3-4 amps total load. They could probably run at 3 amps per channel but...

When searching Ray's website, you will get different results from these searches: WS2811 http://www.aliexpress.com/store/701799/search?SearchText=ws2811 (63 hits) WS2811IC http://www.aliexpress.com/store/701799/search?SearchText=ws2811ic (17 hits) 2811IC...

And for driving even more 5050 chips, there's a 24 volt version: http://www.aliexpress.com/store/product/non-waterproof-DC24V-WS2811-pixel-module-with-12pcs-5050-RGB-SMD-LED-85mm-diameter-pcb-20pcs/701799_701852699.html

And for those interested, thespec sheet for the WS2812, which is a combination of the WS2811 circuit and a 5050 LED. Used for high density pixel displays.

And the spec sheet for the WS2811 chip itself.

From Ray Wu's store, check the circuit diagram to see the booster transistors it takes to drive six of the 5050 LEDs.

I'm interested in the same thing; the ability to control pixels or a GECE with DMX. Cannot do e1.31, but needs to interface with existing theatre dmx systems. Maybe the uDCG-P2?
