ST NUCLEO-F446RE STM32F446RE Nucleo-64 Development Board

The ST NUCLEO-F446RE is a Nucleo-64 development board based on the STM32F446RET6 Arm Cortex-M4 MCU running up to 180MHz. It features 512KB Flash, 128KB SRAM, onboard ST-LINK/V2-1 debugging/programming, Arduino Uno V3-style expansion, and ST morpho headers for broad access to STM32 I/O.

Description

The ST NUCLEO-F446RE STM32F446RE Nucleo-64 Development Board is a flexible development platform for embedded systems, real-time control, robotics, motor control, signal processing, communications, and STM32 firmware development.

At its core is the STM32F446RET6, a 32-bit Arm Cortex-M4 microcontroller with single-precision FPU and DSP instructions, operating at up to 180MHz. The MCU provides 512KB Flash memory, 128KB SRAM, and up to 4KB backup SRAM. STMicroelectronics

The board integrates an ST-LINK/V2-1 debugger/programmer through a USB Mini-B connection, allowing the onboard MCU to be programmed and debugged without a separate external probe. ST documents mass-storage programming, Virtual COM Port, and debug functionality through the onboard ST-LINK. STMicroelectronics

For hardware expansion, the NUCLEO-F446RE provides Arduino Uno V3-compatible headers together with ST morpho headers, giving developers access to a wide range of STM32 I/O and peripheral signals. Power can be supplied through the ST-LINK USB connection or supported external power sources. STMicroelectronics
