WS2812主要特点
●     智能反接保护，电源反接不会损坏IC。
●     IC控制电路与LED点光源公用一个电源。
●     控制电路与RGB芯片集成在一个5050封装的元器件中，构成一个完整的外控像素点。
●     内置信号整形电路，任何一个像素点收到信号后经过波形整形再输出，保证线路波形畸变不会累加。
●     内置上电复位和掉电复位电路。
●     每个像素点的三基色颜色可实现256级亮度显示，完成16777216种颜色的全真色彩显示，扫描频率不低于400Hz/s。
●     串行级联接口，能通过一根信号线完成数据的接收与解码。
●     任意两点传传输距离在不超过5米时无需增加任何电路。
●     当刷新速率30帧/秒时，级联数不小于1024点。
●      数据发送速度可达800Kbps。
●      光的颜色高度一致，性价比高。
