Component

WS2812BRGB LEDaddressable LED4020side-emittingsingle-wire

WS2812B-4020-G1 is a compact 5 V side-emitting RGB addressable LED with an integrated controller and a one-wire cascaded data interface.

Best for

  • Compact RGB indicators
  • Side-emitting decorative lighting
  • Computer peripheral lighting

Avoid if

  • A documented RoHS or REACH declaration is mandatory and separate evidence is unavailable
  • The controller cannot generate WS2812-compatible one-wire timing

Check before use

  • Confirm side-emitting optical orientation
  • Confirm supply-current budget at full white output
  • Follow MSL 5a bake and floor-life controls
