WS2821 Parallel-Single wire-Three channels 256 Gray level Constant current LED driven IC.

Signal adopts the single line parallel connection type,any pixels’ failure won’t effect other pixel’s display effect.
Signal can compatible and expand the DMX512(1990) protocol signal.
Data transmission speed is 250Kbps~750Kbps.
The built-in voltage regulator chip, 5V above 24V power supply only series resistance to IC VDD feet, without additional voltage regulator tube.
WS2821 IC has VR-tube(voltage-regulator tube) built-in,for higher than 5V,lower than 24V’s power.
