Clouduino

Clouduino is a fully open-source, WiFi mesh-enabled embedded development platform.

This project is still in its infancy. At the moment, the circuit design and PCB layout for the initial prototype version is available for building the initial iteration of the board: Clouduino Stratus. We also included sample code to get you started. We will be producing limited quantities of the board soon. In the meantime, let's build our own boards, send us your feed back and help this project grow.
