Intelligent reverse connection protection, calories contrary connection will not harm the IC. The IC control circuit and the LED level proportion a power supply. The leadership circuit and the RGB chip are incorporated in a 3528 packaged element to kind an entire exterior control pixel. Built-in signal shaping circuit, any pixel point receives the signal after waveform shaping and then output, to that waveform distortion won't accumulate. Built-in power-on reset and power-down reset circuits. The 3 of every pixel can achieve 256 levels of brightness display, total the entire exhibit of 16,777,216 colors, and the scanning frequency isn't less than 400Hz/s. The serial cascade interface can get preserve of and decode data by way of way of a sign line. When the transmission distance between any two elements is lower than five meters, there isn't any need to add any circuit. When the refresh commission is 30 frames per second, the variety of cascades isn't always less than 1024 points. The records transmission speed can reach 800Kbps. The coloration of the sunshine is extremely and cost-effective. Colour:white Material:plastic Package Contents: 100x RGB Symphony LED Only the above equipment content, different item should not included. Note: Light and various reveals may cause the color of the object in the photo barely diversified from the genuine thing. The size allowed error is +/- 1-3cm.
