Amazon FreeRTOS is a new operating system for microcontroller-based IoT devices

When you think of IoT devices, chances are you are thinking about a connected camera or sensor. Most of those devices have very basic CPUs and run Linux or a similar operating system. Not every IoT device actually features a real CPU, though. Instead, they are powered by basic microcontrollers. Those devices (think smoke detectors, etc.) are often old and can’t directly connect to the cloud. They tend to run some version of the FreeRTOS operating system and kernel.
