The WeMos d1 mini is an ESP8266 development board that is compact, versatile and very easy to use with the Arduino IDE or PlatformIO IDE. It is supported natively by the Espressive SDK. The advantage of the WeMos d1 mini compared to other ESP8266 development boards lies in the many expansion cards (shields) developed by the Chinese company Wemos.cc.

The shields are stacked on top of the WeMos d1 mini. To facilitate the development and mounting, there is also a double base
and a triple base
There is also a Pro version of the d1 mini. Even finer, it has an IPEX connector to connect an external WiFi antenna to increase the transmission / reception range. It also has 16MB of flash memory instead of 4MB for the standard version. Only memory, the entire flash memory is not yet supported by the Espressive SDK and the Arduino IDE. All shields developed for the d1 mini are compatible with the Pro version. You can find the WeMos d1 min Pro at the best price online.
To start the development of connected objects or accessories for your home automation server, you will find many examples and tutorials here.
