简介
想过要把黄浦江边正旦国际大厦的广告牌搬回家吗?32x16 RGB LED矩阵屏幕可以帮你实现这个愿望。这是一款全彩、高亮LED矩阵屏,常被用在一些广告墙和显示屏上。屏幕采用高分子防火PC塑胶面罩,具备高温阻燃特性和良好的散热性能。可以确保产品的强度和外形稳定性,高低温工作时均能保持模块之间不会相互挤压变形,使产品可以在恶劣环境下正常使用,底壳有便于安装的安装孔,面罩不反光,耐紫外线,不褪色. 该面板由512个RGB led按照32x16网格组成。背后,有两个IDC 连接器,一个输入接口,一个输出接口;1/8扫描驱动显示屏。面板需要用到13个IO 引脚(6个数据位,7个控制位),一个5V电压,2A以上输出电流的电源供电。
注意:此面板在供电和RAM足够的情况下,可以任意级联,组合成一个更大体积的灯板。当级联数量大于4之后,Arduino UNO的运算能力就稍显不足了,需要使用Mega2560,树莓派或者其他的设备来驱动这块RGB面板
