Would the nominal 5V you would get from 4 x NiMH AAA batteries count as 5V for the purposes of running these guys? Would the nominal 6V from 4 x alkaline cells blow them up?
Also, do these controller chips drive the LEDs at a constant current or will my brightness fade with the batteries? I can't actually find a datasheet in English :-)
Cheers, Robert.
I'll try 4xAA (alkaline) cells when I get home after this weekend and see if anything blows up.
I'm reasonably certain these are constant current drivers so you shouldn't fade.I'll try 4xAA (alkaline) cells when I get home after this weekend and see if anything blows up.
No discernible brightness difference. The WS2811 appears to be a constant current driver. (Which I was pretty sure of to begin with).
Setup currently running just fine down to 3.33v.
