Amazon FreeRTOS - Cloud-native IoT operating system for microcontrollers

FreeRTOS is an open source, real-time operating system for microcontrollers that makes small, low-power edge devices easy to program, deploy, secure, connect, and manage. This includes securely connecting your small, low-power devices to AWS cloud services like AWS IoT Core or to more powerful edge devices running AWS IoT Greengrass. FreeRTOS is built with an emphasis on reliability and ease of use.

A microcontroller contains a simple, resource-constrained processor that can be found in many devices, including appliances, sensors, fitness trackers, industrial automation, and automobiles. Many of these small devices can benefit from connecting to the cloud or locally to other devices, but have limited compute power and memory capacity and typically perform simple, functional tasks. Microcontrollers frequently run operating systems that may not have built-in functionality to connect to local networks or the cloud, making IoT applications a challenge. FreeRTOS helps solve this problem by providing the kernel to run low-power devices as well as software libraries that make it easy to securely connect to the cloud or other edge devices, so you can collect data from them for IoT applications and take action.
