The friendly Operating System for IoT!

RIOT is a real-time multi-threading operating system that 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.


RIOT is based on a microkernel architecture, and provides features including, but not limited to:

  • a preemptive, tickless scheduler with priorities
  • flexible memory management
  • high resolution, long-term timers
  • support for AVR, MSP430, ARM7, and ARM Cortex-M on over 50 boards
  • the native port allows to run RIOT as-is on Linux, BSD, and MacOS. Multiple instances of RIOT running on a single machine can also be interconnected via a simple virtual Ethernet bridge
  • IPv6
  • 6LoWPAN (RFC4944, RFC6282, and RFC6775)
  • UDP
  • RPL (storing mode, P2P mode)
  • CoAP
  • CCN-Lite



  • With latest GCC version (>= 6) platforms based on some ARM platforms will raise some warnings, leading to a failing build (see https://github.com/RIOT-OS/RIOT/issues/5519). As a workaround, you can compile with warnings not being treated as errors: WERROR=0 make


If you compile RIOT for the native cpu and include the netdev2_tap module, you can specify a network interface like this: PORT=tap0 make term


There is a shellscript in RIOT/dist/tools/tapsetup called tapsetup which you can use to create a network of tap interfaces.

USAGE To create a bridge and two (or count at your option) tap interfaces:

./dist/tools/tapsetup/tapsetup [-c [<count>]]


To contribute something to RIOT, please refer to the development procedures and read all notes for best practice.
