# RIOT OS: The friendly Operating System for IoT

RIOT is an **open-source microcontroller operating system**, designed to match
the requirements of Internet of Things (IoT) devices and other embedded devices.
It supports a range of devices that are typically found in the Internet of Things (IoT):
*8-bit*, *16-bit* and *32-bit* microcontrollers.

RIOT is based on the following design principles: **energy-efficiency, real-time
capabilities, small memory footprint, modularity, and uniform API access,**
independent of the underlying hardware (this API offers partial POSIX
compliance).

RIOT is developed by an international open source community which is
independent of specific vendors (e.g. similarly to the Linux community).
RIOT is licensed with **LGPLv2.1**, a copyleft license which fosters
indirect business models around the free open-source software platform
provided by RIOT, e.g. it is possible to link closed-source code with the
LGPL code.
