WS2821 Overview
WS2821 Parallel-Single wire-Three channels 256 Gray level Constant current LED driven IC Main.
WS2821 Key Features
- Signal adopts the single line parallel connection type,any pixels’ failure won’t effect other pixel’s display effect
- Signal can patible and expand the DMX512(1990) protocol signal
- Data transmission speed is 250Kbps~750Kbps
- The built-in voltage regulator chip, 5V above 24V
- WS2821 IC has VR-tube(voltage-regulator tube) built-in,for higher than 5V,lower than 24V’s power supply,only require one
- Output voltage can bear 24V
- R/G/B out three channels’ output,each output driven channel has PWM circuit to control the gray,256 gray is adjustable
- R/G/B output default current 19mA,maximum 60mA
- Storage space is built-in,support 1024 pixel’s parallel connection
