I was expecting to be able to set up digital pin 0 on the Wemos D1 Mini and have it “Just Work.” It turns out the Arduino pins don’t match up neatly to the Wemos D1 Mini pins. The path of true love, eh? Luckily,Richard Lee mapped the Wemos pins to the Arduino pinswell al...
The most widely used ESP8266 boards are theESP-01,ESP8266-12E NodeMCU Kit, and theWemos D1 Mini. For a comparison of these board, you can read this guide:ESP8266 Wi-Fi Development Boards comparison. ESP8266-01 Pinout If you’re using an ESP8266-01 board, you can use the following G...
Esp8266 12E module has a total 22 pins which include ESP8266 12E Wemos D1 Mini pinout Wemos D1 Mini development board has a total 16 pins in which 12 pins are active, uses ESP-12 module, onboard reset button, 3.3 voltage regulator, Micro USB, USB to UART bridge and some other compon...
Important!While it shows 3.3V and the datasheet says so, the 3V pin is indeed 3V only! Connecting a 3.3V device won’t work so be aware. These are the boards that carry the “NodeMCU” name. But they are not the only ones featuring the ESP8266. SeeAdafruit HuzzahandWeMos D1 Mini....
