    Question WS2801 vs. WS2811

    Just read today about the transition from WS2801 to WS2811. Aside from being a little less expensive (yay!), will there be any performance or programming differences? Will I be able to commingle the 2801 and 2811 pixels on the same controller without problems and without the audience telling the difference? Thanks.

    The dimming properties are the same on both chips. The WS2811 uses 3 wire as opposed to the 4 of the 2801. My manufacturer has told me the WS2811 is also more "stable", but I have yet to have a problem with the WS2801 chips.

    You should be able to comingle the strings. How you configure your controller for that depends on the controller. If using an e68X you would have to put the WS2811 on different universes than the WS2801. Also, you'll have to check the firmware version of your e68x. There was a firmware update which added functionality for the WS2811 IC.

    The WS2811s use timing very similar to the 1804s. With the most recent firmware of the E68x controllers, select 1804 (fast) as the chip type.
