A curated list of awesome open source IoT frameworks, libraries and software.

Note that the list only features components we think are particularly relevant for IoT (e.g they are appropriate for use in embedded IoT devices, deal with the specific constraints of IoT communication networks, etc.). The reader will want to refer to the [Awesome](https://github.com/sindresorhus/awesome) catalog for more references in his/her programming language or technical field of choice.
