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.

Note: Unlike Espruino Pico and the original Espruino board, Espruno WiFi doesn't contain any battery switchover circuitry. The +/+VUSB pin is connected straight to USB 5V, and shouldn't be used to power the WiFi board while Micro USB is plugged in, unless it is via a diode from 5V.
