FreeRTOS is a real-time operating system for a variety of microcontrollers and has been used in the industry for years. Due to the trend of networking, Amazon uses FreeRTOS as a base and integrates network stacks, security, encryption, online updates, and provides the connectivity to Amazon Web Services. Through the Ethernet or Wi-Fi, the end devices can directly communicate with local Amazon Greengrass or connect to the AWS IoT service in the cloud, combined with other Amazon services, such as Alexa, DynamoDB, Lambda, etc. to create innovative IoT applications.
Nuvoton is Amazon’s partner. The NuMaker IoT development platform is built with NuMicro® series of microcontroller M487. It has Ethernet and Wi-Fi networking capabilities and fully certified to support Amazon FreeRTOS to work with AWS IoT service. Keil MDK is used as a development tool, and the built-in Nu-Link on the platform can be used for firmware download and debugging.

The NuMaker IoT-M487 integrates common components and multiple expansion interfaces. It has Ethernet and Wi-Fi connectivity. The microcontroller is a NuMicro® M487 with a Cortex-M4 core and a clock rate up to 192MHz, 512K bytes Flash, and 160K bytes SRAM. Built-in hardware crypto accelerator improves the efficiency of data encryption and network transmission. It can be used in applications, such as sensor node, light-weight gateway, keyword speech recognition, text image recognition, and more.
The Amazon FreeRTOS development kit for NuMaker IoT-M487 can be downloaded from the Amazon FreeRTOS web page, including an example of connecting to AWS IoT services, reducing the barrier of development. More examples continue to be launched on the Nuvoton web site.
