Overview
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. Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of software libraries suitable for use across industry sectors and applications. This includes securely connecting your small, low-power devices to Amazon Web Services cloud services like Amazon IoT Core or to more powerful edge devices running Amazon 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 do 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.
Benefits
Open source
FreeRTOS is released under the MIT open source license, a permissive license with limited restrictions on reuse. To learn more about the FreeRTOS open source community, please click here.
Trusted kernel
The FreeRTOS kernel is trusted by world-leading companies as the de facto standard for microcontrollers and small microprocessors with proven robustness, tiny footprint, and wide device support.
Accelerate time to market
FreeRTOS includes IoT reference integrations, which are pre-integrated FreeRTOS projects ported to microcontroller-based evaluation boards that demonstrate end to end connectivity to the cloud, and pre-configured demos that can help you quickly get started with a project. You can instantly download code and compile to accelerate time to market.
Securely program, deploy, and manage low-power devices
FreeRTOS includes support for Transport Layer Security (TLS v1.2) to help your devices connect securely to Amazon Web Services. You can also easily program commonly needed IoT capabilities into your device, including software 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. FreeRTOS also includes an over-the-air (OTA) update library to remotely update devices with feature enhancements or security patches and a code signing feature to ensure your device code is not compromised during deployment and OTA updates.
Broad ecosystem support
The FreeRTOS partner ecosystem provides a breadth of support including community contributions, professional support, and integrated development and productivity tools. FreeRTOS gives you the flexibility to easily build IoT solutions on a variety of chipsets and supports over 40 architectures. You can find devices that have been qualified to work with FreeRTOS on the Amazon Partner Device Catalog, a curated catalog of Amazon Web Services enabled hardware from our trusted APN partners.
Validate your FreeRTOS devices
Amazon IoT Device Tester for FreeRTOS is a test automation tool that makes testing your choice of devices easy. You can use the Amazon IoT Device Tester to confidently self-test if your devices will run FreeRTOS and interoperate with Amazon IoT services.
How it works
FreeRTOS provides everything you need to easily program connected microcontroller-based devices and collect data from them for IoT applications. You can get started by choosing an FreeRTOS-qualified microcontroller from the Amazon Partner Device Catalog. Then, you can use the FreeRTOS console or GitHub to select and download relevant FreeRTOS libraries or pre-validated IoT reference integrations. Visit our getting started page to learn more about all the options.
You can securely connect FreeRTOS devices to cloud services like Amazon IoT Core, to a local edge device, or to a mobile device via Bluetooth Low Energy, and update them remotely using the OTA update feature available with Amazon IoT Device Management. An integration with Amazon IoT Device Defender makes it easy to report on device-side metrics to detect anomalies when these metrics deviate from expected behavior.
