The jointly created solution combines ST's STM32U5 ultra-low-power microcontrollers (MCUs), FreeRTOS open-source real-time operating system, and Arm® trusted-firmware for embedded systems (TF-M). The reference implementation is realized on ST's B-U585I-IOT02A discovery kit for IoT nodes with STM32U5 MCUs, which contains rich features including USB, Wi-Fi®, and Bluetooth® Low Energy connectivity, as well as multiple sensors. The STSAFE-A110 secure element support is being added and comes pre-loaded with IoT object credentials. It helps secure and simplifies attachment between the connected objects and the AWS cloud. FreeRTOS comprises a kernel optimized for resource-constrained embedded systems and software libraries for connecting various types of IoT endpoints to the AWS cloud or other edge devices.
