ESP8266 只有一个引脚支持模拟输入,此引脚叫 ADC0,丝印上常标记为 A0。 如果使用 ESP8266 裸芯片(ESP-12E/F)的话,此引脚的电压输入范围为 0-1V。如果使用了 NodeMCU 之类的开发板,那么电压输入范围就是 0-3.3V,因为开发板上已经集成了分压器。 板载LED 大多数 ESP8266 模块均有一个内置的 LED,通常连在...
各引脚分别作为输入输出时的推荐程度和注意事项说明,图片截图自:https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/ ESP12引脚图,引脚图适用于12E/F,以及原版8266模块 其实图表已经把功能成系列的引脚归类排列在一起了,根据注意事项翻译过来就是: GPIO0(D3):连接到NODEMCU为代表的FLASH按键开关上,作...
