Addressable

WS2813A-B-V1Worldsemi5050 RGB LEDaddressable LEDGRB protocoldual signal input

WS2813A-B-V1 is a 5050 intelligent RGB LED for individually controlled lighting strings and displays. It integrates the LED driver and controller and supports a redundant DIN/BIN signal-input arrangement.

Best for

  • Addressable decorative LED lighting
  • Individually controlled RGB pixel strings
  • Consumer and gaming lighting effects

Avoid if

  • A non-addressable RGB LED is required
  • The controller cannot generate WS281x-compatible timing
  • Moisture-sensitive SMT handling cannot be controlled

Check before use

  • Use GRB byte order with most-significant bit sent first
  • Hold the data line low for at least 280 µs to latch a frame
  • Route primary DIN and auxiliary BIN according to the redundant-signal design
  • Review power distribution for the total LED load
