Description

The Espruino WiFi is a tiny WiFi-enabled board that runs JavaScript code (it doesn't need to be plugged into a computer). You can program it with nothing but a serial terminal program, but there's also an IDE that runs in the Chrome Web browser. It's got a syntax highlighted editor as well as a graphical programming language.
