Title: Raspberry Pi 3 GPIO & WS281X

In the wiki it says that model 3 can support up to 48 strings, web gui still says GPIO 18 + 19, 24 strings per GPIO sounds much or how do I connect?

I'm pretty sure that is an error and should say 2 strings.  Along time ago I think it was 48 nodes per output, but that has been upped to at least 1000 per output.  Of course that is just the data and not power.

Ok, thanks Jim.

you are limited to 800 to 1000 pixels per output.  Pi ver3 can support two outputs.  Will need a converter to boost output from 3.3 v to 5v.
