Intelligent reverse connection protection ensures the IC will not be damaged by power reverse connection. The IC control circuit and LED point light source share a power supply. The control circuit and RGB chip are integrated in a 3528 packaged component to form a complete external control pixel. Built-in signal shaping circuit; each pixel receives and reshapes the signal before output, preventing cumulative waveform distortion. Built-in power-on reset and power-down reset circuits. Each pixel's three primary colors achieve 256 brightness levels, enabling full true color display of 16,777,216 colors with a scanning frequency of at least 400Hz. Serial cascade interface allows data reception and decoding through a single signal line. No additional circuit is required when transmission distance between any two points is under 5 meters. At a refresh rate of 30 frames per second, supports no fewer than 1024 cascaded points. Data transmission speed up to 800Kbps. High color consistency and cost-effective.
