Simplifying IoT-Node Connectivity and Security to Amazon Web Services

Solution Description


It can be difficult to manage all the data streaming in from the many sensors streaming in from an IoT node, not to mention the device management with firmware upgrades, new feature deployment, etc…

These problems, however, can be managed far better if the node is able to handle communicate directly with a centralized cloud service. Then all data are analyzed quickly and in real-time, allowing enterprises to get the maximum benefit.

This solution aids in the creation of smart connected low-power devices. It enables users to develop a wide diversity of applications by exploiting low-power communication with AWS cloud servers and its native services including standard Firmware Over The Air (FOTA) updates.

The solution is based on an STM32L4+ microcontroller and an extensive selection of ST MEMS sensors (detection, environmental awareness) and low-power multilink communication (Bluetooth® Low Energy, Sub-GHz).

  • Key Product Benefits

    STM32L4S5VIT6 Ultra-Low power MCU

    Ultra-low-power Arm® Cortex®-M4 microcontroller. It embeds 2MB Flash, 640KB RAM, digital and analog peripherals, and hardware encryption accelerator.
