Breakpoint Resume Transmission: Dual-signal line design ensures continuous operation; if one LED is damaged, the rest of the chain keeps functioning normally.
Dedicated White Channel: Integrated RGBW chip with CCT configurable from 2700K to 7000K, delivering pure, high-quality white light alongside vivid colors.
High-Fidelity Grayscale: 8-bit (256 levels) per channel provides ultra-smooth color gradients and precise dimming without visible stepping.
Simplified Single-Wire Control: Uses a single-line zero-code protocol for easy MCU interfacing, reducing wiring complexity and saving PCB space.
Broad Voltage & Stable Drive: Operates reliably at 4.0V–5.3V with a constant 16mA drive, ensuring consistent brightness and color accuracy across long runs.
