(SKU:DFR0472)32x32 RGB LED Matrix - 4mm pitch

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。
