The WeMos D1 Mini (V2) class of ESP8266 WiFi enabled 32 bit micro controller development boards are compatible to Lua Script and Arduino IDE, coming with 4MB Flash Memory, and 80MHz clock speed. ESP8266 based development boards are the perfect core for your Internet Of Things project, or tiny web server.

This very popular 2.4GHz WiFi module (802.11b/g/n) is almost 10 times faster than an Arduino Uno, and comes with plenty of memory. After installing the board file, the Arduino IDE can be used to develop and upload programs to the Wifi module. The header can be used to attach other WeMos D1 form factor compatible shields.

The D1 Mini is a WiFi capable ESP8266 based development board, and it is compatible with the Arduino IDE and with NodeMCU (Lua Script). WeMos D1 features 11 GPIO pins (input/output/PWM/IC), thereof 1 UART (RX/TX) for serial communication, and 1 additional analog input. Please pay attention when you connect other active periphery to the I/O pins, because this is a 3.3V logic level device and higher levels on any pin will destroy it. The max. input voltage for the analog pin is 3.2V.

Attention: This is a 3.3V logic level device!

Please follow these 3 steps to get started:

  1. Install USB driver support for CH340G USB-UART bridge: download
  2. Add WEMOS D1 Mini board support to Arduino IDE:
    • Open Arduino IDE, go to File -> Preferences
    • Enter this Address to “Additional Boards Manager URLs”:
    • Go to Tools -> Board: -> Boards Manager
    • Filter your Search “wemos”
    • Install the “ESP8266 by ESP8266 community” package
  3. Connect your D1 Mini to your Windows PC, and upload the BLINK sketch: download
