WS2813B-V5
Category
The WS2813B-V5 RGB LED module with integrated controller offers cost-effective color illumination for consumer electronics, industrial displays, and smart systems. Its fixed wavelength output (623nm red, 520nm green, 471nm blue) and built-in driver simplify circuit design while maintaining 150mcd brightness. Designed for 3.3-5V operation with thermal resistance 35°C/W, it requires careful soldering and thermal management to prevent reliability issues. The product is positioned as an affordable alternative to discrete RGB components but lacks advanced dimming features and extended temperature tolerance compared to premium offerings.
