Unit RGB is a smart LED strip unit that integrates three SK6812 programmable RGB LEDs. Through programming, users can independently control the color and 256-level fine brightness of each LED to achieve rich lighting effects. Its unique daisy-chain design allows multiple units to be easily expanded, forming longer light strips or complex lighting arrays. The unit is equipped with LEGO-compatible mounting holes, making it convenient to install in various structures or projects. It is an ideal… (M5Stack U003)
