Intelligent reverse connection protection, power reverse connection will not damage the IC.<br> The IC control circuit and the LED point share a power supply.<br> The control circuit and the RGB chip are integrated in a 3528 packaged component to form a complete external control pixel.<br> Built-in signal shaping circuit, any pixel point receives the signal after waveform shaping and then output, to that waveform distortion will not accumulate.<br> Built-in power-on reset and power-down reset circuits.<br> The three of each pixel can achieve 256 levels of brightness display, complete the full display of 16,777,216 colors, and the scanning frequency is not less than 400Hz/s.<br> The serial cascade interface can receive and decode data through a signal line.<br> When the transmission distance between any two points is less than 5 meters, there is no need to add any circuit.<br> When the refresh rate is 30 frames per second, the number of cascades is not less than 1024 points.<br> The data transmission speed can reach 800Kbps.<br> The color of the light is highly consistent and cost-effective.<br> Colour:white<br> Material:plastic<br> Package Contents:<br> 100x RGB Symphony LED<br> Only the above package content, other products are not included.<br> Note: Light 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.
