    Not sure about that data sheet - either way it's WS2811 compatible which is 5V based signaling.

    I'll have to try a ESPixelStick with it and see if the GS8208 will take 3.3V signaling too. :)

    Those figures are the maximum working range (without damage) figures. Page 4 has the VIL and VIH figures although they seem to be somewhat screwed up. I think they mean VIL (logic 0) is 1V max and VIH (logic 1) is 4V min ? Maybe there's a more complete data sheet out there.

    Hey thanks, I went with a 74HCT08 AND gate as a logic level shifter, and it seems to work OK. Nice clean 5v output.

    When I hooked up the board to the lights however, I get no LED output. When the power turns on, all the LEDs shine white for a fraction of a second, so I think they are good strips.

    When I measured the output from the ESPixelStick driver (NodeMCU from Banggood) I noticed that the edge to edge speed was 746KHz - is this too much drift from the spec 800kHz ?

    That's the only reason I can think of why the lights would not be working.
