Just spent a few hours messing with these and the test pattern on my e682, quadruple checking everything I could for wiring....but oh my god the diagrams people use for showing the pinouts seem to diff everywhere you go? http://www.aliexpress.com/store/product/100nodes-DC12V-WS2811-LED-technicolor-pixel/701799_922162404.html I have 400 of these and need to know the actual pinout, is the Arrow side ground or +12v? I believe middle is data. The picture shown is wrong on one side since they both have the reversed pins connected for +12v and ground. I am using http://www.aliexpress.com/store/product/10pcs-lot-3-Core-BLACK-Waterproof-pigtail-20cm-long-each-male-and-female-male-connector-s/701799_1019853359.html these pigtails, which is which for colours? Brown, yellow and blue. Yellow I believe is data. I wish they at least labelled the wires somewhere on the pixels or better yet the connectors.
