Introducing Zephyr
##################
The Zephyr kernel is a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental
sensors and LED wearables to sophisticated smart watches and IoT
wireless gateways.
The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and LED
wearables to sophisticated smart watches and IoT wireless gateways.
It is designed to be supported by multiple architectures, including
ARM Cortex-M, Intel x86, and ARC. The full list of supported boards
can be found :ref:`here <boards>`.
