Intelligent reverse connection protection, reverse power 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, any pixel point receives the signal after waveform shaping and then outputs, to ensure that the line waveform distortion will not accumulate. Built-in power-on reset and power-off reset circuits. The three primary colors of each pixel can achieve 256 brightness levels, complete full true color display of 16,777,216 colors, and the scanning frequency is not less than 400Hz/s. The serial cascade interface can receive and decode data through one signal line. When the transmission distance between any two points is less than 5 meters, no circuit needs to be added. When the refresh rate is 30 frames per second, the number of cascades is not less than 1024 points. The data transmission speed can reach 800Kbps. The color of the light is highly consistent and cost-effective. Color: white Material: plastic Package Contents: 200 * RGB Symphony LED Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
