E1.31 DMX

E1.31

WLED supports the E1.31 (sACN) realtime light protocol. I highly recommend the LedFx project! 170 LEDs (510 DMX channels) are supported per universe. You can use up to 9 adjacent universes which is a total of more than the maximum 1500 LEDs WLED can drive. For a fluent 25ms (40fps) or more framerate, it is recommended to use no more than 3 universes (510 LEDs).

LedFx users: If you want to use more than 170 LEDs, you need to go to additional settings and set "Universe Size" to 510 when adding the WLED device!
