我的HDMI购买地址买了一个5路带红外遥控的
摘掉原有的5个led灯，晚上太亮瞎眼（主要是分压不亮了，我又不会处理
）正极接在我们的小板子上，负极不用管，整个板子的GND都是相通的。EDA打开，新建工程HDMI.json (120.6 KB)
板子问题有很多，毕竟我已经打完了就不改了 
问题1 ：红外发射头用的tx脚，这个烧录的时候就会出现问题了，可以做一个跳帽，用的时候帽上，刷机的时候摘下来；
问题2 ：空间有点小最后盖上中间会翘起来，光耦应该放在底层。
问题3：这个红外外接的时候要注意线别焊错地方了，要不然没电压
还有这个红外接收头可以更美观的处理下
还有很多小问题 啥电阻电容啊都不会加
毕竟我是菜鸟一只。
本来用的esphome结果红外有问题解决不了，又学了学arduino 
红外码请用这个获取IRrecvDumpV2.zip (3.1 KB) 打开串口调试，按下遥控按钮就会看到红外
记下，等会写在arduino里
