NUCLEO-G491RE development board
The NUCLEO-G491RE is a high-performance STM32 Nucleo-64 board with an ARM Cortex-M4 MCU (170 MHz, 512 KB Flash), ideal for IoT, robotics, and embedded development.
Description
The NUCLEO-G491RE Development Board from STMicroelectronics is a powerful and versatile STM32 Nucleo-64 board built around the STM32G491RE microcontroller (ARM® Cortex®-M4 core running at 170 MHz). It provides high computational performance, rich peripherals, and flexible power options, making it ideal for embedded system development, IoT, motor control, and industrial automation applications.
This Nucleo board features Arduino Uno V3 and ST morpho connectors for easy hardware expansion, supporting a wide range of shields and accessories. Developers can program and debug using the ST-LINK/V2-1 interface (built-in), and the board is compatible with STM32CubeIDE, Keil MDK, IAR EWARM, and Arduino IDE (via STM32duino).
Its robust design, low power consumption, and comprehensive software ecosystem make it a go-to choice for engineers, students, and professionals seeking a reliable and cost-effective STM32 prototyping platform.
