ESP8266 Arduino Style MicroPython Development Board
Easily harness the powerful ESP8266 WiFi-enabled microcontroller with the excellent microPython programming environment using this ESP8266 Arduino Style MicroPython Development Board from PMD Way.
As you can see, the board uses the popular Arduino Uno R3-type form factor, giving you outstanding hardware compatibility - and the board arrives preloaded with microPython so you can get started with coding very quickly.
MicroPython is a tiny open source Python programming language interpretor that runs on small embedded development boards.
With MicroPython you can write clean and simple Python code to control hardware instead of having to use complex low-level languages like C or C++ (what Arduino uses for programming).
