The D1 is an ESP8266 microcontroller built with the same form factor as an Arduino Uno. It’s the best starting point to get familiar with the newer controller if you’ve used Arduino in the past. Compared to all of the Arduino models the ESP8266 is superior in every way. That’s not even taking into account that the ESP8266 has integrated WiFi which allows for development of internet of things projects. This board is a must have for anyone building projects and products with electronics.
The D1 is well supported and is programmable with the Arduino IDE as well as others such as XOD Visual Programmer.
