STM32 NUCLEO-G491RE - STM32G491RE ARM Cortex M4

STM32 Nucleo module with a 32-bit STM32G491RE microcontroller, which is equipped with anArm Cortex-M4core clocked up to 170 MHz, 512 kB of Flash memory and 96 kB of SRAM. As the board belongs to Nucleo-64 family, it iscompatible with mbed platform, has connectors to connect Arduino Uno based overlays andST morphopins which give access to all microcontroller GPIO pins. It works with wide range of Integrated Development Environments (IDE) like IAR Embedded Workbench, MDK-ARM and STM32CubeIDE. Device is equipped with ST-LINK debugger / programmer.

Using connectors compatible withArduino Uno v3, allows direct connection ofdedicated Shield extensions.
