Intelligent reverse connection protection ensures that power reverse connection will not damage the IC. The IC control circuit and the LED point light source share a power supply. The control circuit and the RGB chip are integrated in a 3528 packaged component to form a complete external control pixel. Built-in signal shaping circuit; each pixel receives the signal after waveform shaping and then outputs it, ensuring that line waveform distortion does not accumulate. Built-in power-on reset and power-down reset circuits. Each pixel can achieve 256 levels of brightness for the three primary colors, enabling full true color display of 16,777,216 colors, with a scanning frequency of at least 400Hz. The serial cascade interface allows data to be received and decoded through a single signal line. When the transmission distance between any two points is less than 5 meters, no additional circuitry is required. At a refresh rate of 30 frames per second, the number of cascaded points is no less than 1024. Data transmission speed can reach 800Kbps. Light color is highly consistent and cost-effective.
