Amazon FreeRTOS

IoT operating system for microcontrollers

Amazon FreeRTOS (a:FreeRTOS) is an operating system for microcontrollers that makes small, low-power edge devices easy to program, deploy, secure, connect, and manage. Amazon FreeRTOS extends the FreeRTOS kernel, a popular open source operating system for microcontrollers, with software libraries that make it easy to securely connect your small, low-power devices to AWS cloud services like AWS IoT Core or to more powerful edge devices running AWS IoT Greengrass.

A microcontroller (MCU) is a single chip containing a simple processor that can be found in many devices, including appliances, sensors, fitness trackers, industrial automation, and automobiles. Many of these small devices could benefit from connecting to the cloud or locally to other devices. For example, smart electricity meters need to connect to the cloud to report on usage, and building security systems need to communicate locally so that a door will unlock when you badge in. Microcontrollers have limited compute power and memory capacity and typically perform simple, functional tasks. Microcontrollers frequently run operating systems that do not have built-in functionality to connect to local networks or the cloud, making IoT applications a challenge. Amazon FreeRTOS helps solve this problem by providing both the core operating system (to run the edge device) 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.

To get started, you can select a device from the AWS Partner Device Catalog. Then, you can use the Amazon FreeRTOS console to download Amazon FreeRTOS for your device or download from GitHub. Amazon FreeRTOS is open source and there is no charge to use it. To learn more about getting started, click here.

What is Amazon FreeRTOS?

Benefits

Extends the FreeRTOS Kernel

Amazon FreeRTOS is open source and it extends the FreeRTOS kernel, the most popular real-time operating system for microcontrollers. With Amazon FreeRTOS, you can take advantage of the large ecosystem of existing tools developed for the FreeRTOS kernel. If you are already using the FreeRTOS kernel on your existing devices, you can choose to use Amazon FreeRTOS and take advantage of the functionality provided by the additional libraries, or continue to use just the kernel operating system.

Easily Program, Deploy, and Manage Low-Power Connected Devices

Amazon FreeRTOS includes software libraries that make it easy to program commonly needed IoT capabilities into your device, including libraries that help configure devices to a local network using common connectivity options like Wi-Fi or Ethernet, or connect to a mobile device using Bluetooth Low Energy (BLE).

Amazon FreeRTOS How It Works

Use Cases

Industrial Applications

Industrial customers utilize microcontroller-based devices that generate data about business critical workloads. Industrial sensors, actuators, pumps, and components of automation utilize microcontrollers because they are low-cost, low-power, and can perform real-time actions. For instance, a single pump on an oil rig is controlled by a microcontroller and has the potential to completely shut down production if there is a failure. Amazon FreeRTOS enables these customers to collect data on system performance and stress through a direct connection to the cloud, and to take critical, local actions in real-time with AWS IoT Greengrass to prevent such disruptive outages.

B2B Solutions

Microcontrollers are commonly used in B2B commercial devices because of their low-power requirements and low cost. For example, security equipment manufacturers are increasingly adding connectivity to microcontroller-based devices like commercial door locks and sensor systems. Amazon FreeRTOS allows these companies to accelerate the release of new connected products by simplifying the design and development process. Development is simplified because the AWS Partner Device Catalog lets you quickly find and purchase Amazon FreeRTOS qualified microcontrollers. These manufacturers can also securely apply patches to commercial door locks with the OTA update feature.

Consumer Products

Amazon FreeRTOS can help consumer products companies like appliance, wearable technology, or smart lighting manufacturers standardize microcontroller-based device development, delivery, and maintenance across a wide variety of products and models. Amazon FreeRTOS provides a single microcontroller operating system that can support a wide range of microcontroller hardware of varying power and capacity. This lets these companies focus on product innovation instead of managing the complexity of software development across multiple product lines. Amazon FreeRTOS also provides the ability to securely update features of existing consumer products in the field with the OTA update feature.
