GPIO4/5引脚小结:I2C的时钟和数据引脚,同时也适合别作他用,用作输入输出引脚,同时4号脚支持PWM输出; GPIO6-11 未在此图中被引出,因为它们用于连接大多数模块上的闪存芯片。如果将这些引脚用作 IO 使用将会导致程序崩溃。 需要注意的是,某些开发板和模块(ESP-12ED、NodeMCU 1.0)也会断开引脚 9 和 11。如果烧...
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 GPIO2 上。LED 亮灭的逻辑是反向的,GPIO2 为高电平时,LED 熄灭;GPIO2...

The I2C pins stated above are set in default. If we want to change the GPIO pins we have to set them in code. The diagrams below show the pinout for the ESP32 and Esp8266 respectively. ESP32 I2C Pins ESP8266 I2C Pins The following figure shows the I2C pins of ESP8266 NodeMCU: ...
在这一点上,GPIO引脚与Arduino开发板的引脚功能十分类似。请留意:在很多介绍ESP8266以及NodeMCU的资料里会出现两种引脚命名方法。一种是GPIO编号,一种是NodeMCU引脚名。请注意这两者是不同的,请千万不要混淆。GPIO编号指的是ESP8266芯片的引脚编号如下图所示: 而...
