es 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 supply,only require one resistor being series connected to the IC’s VDD pin,no need to add the VR-tube outside.
