Tessel

"Tessel is an open-source microcontroller that is programmable in JavaScript and compatible with Node.js. We founded Technical Machine to make hardware development as fast and flexible as developing for the web. Tessel is the first step in that mission.

Tessel is optimized for the creation of new experiences and internet-connected devices. That’s why Tessel features built in WiFi support and “plug and play” modules that can be installed with one line to the Node package manager (npm). By enabling rapid prototyping and iteration, Tessel gives hardware development the speed and flexibility of web development."
