How it works

FreeRTOS is an open-source, cloud-neutral real-time operating system that offers a fast, dependable, and responsive kernel. FreeRTOS is freely distributed under the Massachusetts Institute of Technology (MIT) open-source license and implemented in over 40 architectures, providing developers with a broad choice of hardware along with a set of prepackaged software libraries.
