November 27, 2020 by Mouser Electronics

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.


STMicroelectronics STM32L4+ Discovery kit for IoT node is a flexible platform for applications with a direct connection to the cloud. 

The kit is based on an ultra-low-power STM32L4+ series MCU with a 120MHz Arm Cortex-M4 processor with FPU. It includes a Wi-Fi module for easy connection to cloud services and the STSAFE-A110 secure element for authentication and secure data management. A Bluetooth module and dynamic NFC tag provide additional connectivity options. 

The board includes a wide range of sensors, providing environmental monitoring, motion tracking, gesture recognition, and more, and hardware capabilities can be expanded using the Arduino® Uno or Pmod expansion connectors. The kit also features an on-board ST-LINK debugger/programmer, with example code and comprehensive libraries available in the STM32Cube MCU Package.
