Intelligent reverse connection protection, calories contrary connection won't harm the IC. The IC control circuit and the LED point share an influence supply. The control circuit and the RGB chip are incorporated in a 3528 packaged factor to sort a complete outdoors leadership pixel. Built-in sign shaping circuit, any pixel level receives the signal after waveform shaping after which 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 stages of brightness display, total the entire display of 16,777,216 colors, and the scanning frequency isn't lower than 400Hz/s. The serial cascade interface can obtain and decode news through a signal line. When the transmission distance between any two elements is less than 5 meters, there's no need to add any circuit. When the refresh payment is 30 frames in keeping with second, the range of cascades isn't lower than 1024 points. The news transmission velocity can attain 800Kbps. The coloration of the sunshine is very and cost-effective. Colour:white Material:plastic Package Contents: 100x RGB Symphony LED Only the above equipment content, different merchandise will not be included. Note: Light and diverse exhibits could cause the colour of the thing within the photo a bit different from the real thing. The dimension allowed error is +/- 1-3cm.
