STMicroelectronics NUCLEO-F446RE development board
The NUCLEO-F446RE is a high-performance Nucleo-64 STM32 development board with ARM Cortex-M4 MCU, Arduino-compatible headers, and onboard ST-LINK debugger.
The STMicroelectronics NUCLEO-F446RE is a powerful Nucleo-64 development board designed for rapid prototyping and embedded system development with STM32 microcontrollers. It features the STM32F446RE MCU, a 32-bit ARM Cortex-M4 processor with FPU, running at 180 MHz, with 512 KB Flash memory and 128 KB SRAM, offering high performance for demanding applications.
The board comes with Arduino Uno R3-compatible headers and ST morpho expansion headers, enabling easy interfacing with shields, sensors, and modules. It also integrates an ST-LINK/V2-1 debugger/programmer, eliminating the need for external debugging tools.
Fully supported by STM32CubeIDE, Keil, and IAR Embedded Workbench, the NUCLEO-F446RE is ideal for IoT devices, robotics, industrial automation, motor control, signal processing, and educational training. Its high-speed performance and versatile connectivity make it perfect for both beginners and professional developers.
