STM32L4 microcontrollers offer dynamic voltage scaling to balance power consumption with processing demand, low-power peripherals available in Stop mode, safety and security features.

NUCLEO-L476RG Nucleo-64 Development Board

From StMicroelectronics, the NUCLEO-L476RG development board features an ultra-low power Arm Cortex M4 STM32L476RGT6 microcontroller in an LQFP64 package. This development board enables you to easily build and evaluate prototypes. The microcontroller features a set of power saving modes that will help you to prototype designs with power consumption limitations.

Arduino Uno v3 and ST morpho headers allow you to easily connect with a range of specialised shields and vastly expand the functionality of your development board.
A Floating Point Unit (FPU) supports all ARM single precision data-processing instructions and data types. This STM32 development board also has an MPU (Memory Protection Unit) which significantly enhances the security of your applications.

The NUCLEO-L476RG has an integrated ST-LINK/V2-1 debugger and programmer which is provided with preinstalled HAL Library software and other packaged software. Tools such as ARM mbed on-line resources mean that you can start developing prototypes immediately. This board is also supported by other IDEs (Integrated Development Environments) such as GCC-based IDEs, IAR and Keil.
