I have a SanDevices E6804 and a Raspberry Pi B v3, but I see in the wiki that the BBG or BBBWL can drive up to 48 strings of WS2811 directly off the GPIO. How well does this work? I'm creating a beer bottle grid wall in my backyard with about 400 pixels. I was going to use the e6804 for it but if the BBG or BBBWL will work just as well for that purpose, it would be a cheaper option and fewer components. Then I can re-purpose the e6804 for use in my christmas display.
