  • Espruino WiFi - High Power STM32F4 with an ESP8266 Running JavaScript

    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. It's a high power STM32F4 with an ESP8266 in a tiny package running JavaScript!

    Once you've uploaded code, you can inspect and change variables (including functions!) while your program is running. There's loads of documentation, tutorials, and support for a huge range of different hardware too.
