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...

ESP8266芯片的GPIO引脚可用作数字输入来读取引脚电平,也可用作数字输出向外围电路发出控制信号。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...
ArduCAM now released a ESP8266 based Arduino board for ArduCAM mini camera modules while keeping the same form of factors and pinout as the standard Arduino UNO R3 board. The high light this ESP8266 board is that it well mates with ArduCAM mini 2MP and 5MP camera modules, supports Lithium...
If you take a look at the NodeMCU pinout, you can see that GPIO 16 is a special pin and it has a WAKE feature. Recommended reading:ESP8266 Pinout Reference Guide The RST pin of the ESP8266 is always HIGH while the ESP8266 is running. However, when the RST pin receives a LOW signal...
