32x32 RGB LED Matrix - 4mm pitch

简介

这款正方形小间距的LED面板可以显示很细腻的图案,彩色,字母等效果。32x32的灯珠,小体积面板,可以让你级联出不同形状的面板,比如级联一个小正方体的形状,做出立体的显示效果,是不是特别有趣? 32x32 RGB LED Matrix - 4mm pitch是一款全彩、高亮度、寿命长、色彩纯正、无污染LED显示模组,此模组采用高分子防火PC塑胶面罩,套件采用具耐高温阻燃特性的pc材料,具有良好的散热性能,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。

注意
  1. 此面板在供电和RAM足够的情况下,可以任意级联,组合成一个更大面积的灯板。当级联数量大于2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

  2. 如果使用mega,连接方式请参考这里。 |
