STM32 Nucleo-F446RE Development Board

Description

The STM32 Nucleo-F446RE Development Board is an affordable and flexible open-source prototyping board by STMicroelectronics that allows users to build custom concepts and applications with high-performance STM32 microcontrollers.

Key Features & Specifications

• Microcontroller: Features the STM32F446RET6 (LQFP64 package), an ARM 32-bit Cortex-M4 CPU featuring an FPU (Floating Point Unit) and an Adaptive Real-Time (ART) Accelerator operating at up to 180 MHz.

• Memory: Includes 512 KB of Flash memory and 128 KB of SRAM.

• Connectivity Options:

  • Arduino™ Uno V3 connectivity support.

  • ST Morpho extension pin headers, providing full access to all available MCU I/Os.

  • Comprehensive communication interfaces including SPI, I2C, USART, UART, USB OTG, and dual CAN interfaces.

• Integrated Debugger/Programmer: Features an on-board ST-LINK/V2-1 debugger/programmer with USB re-enumeration capabilities (supporting mass storage, virtual COM port, and debug port), eliminating the need for a separate probe.

• Flexible Power Supply: Can be powered via USB VBUS (5V) or through external sources such as a 3.3V, 5V, or 7–12V DC power supply.

• User Interface Elements: Includes 3 LEDs (for power, USB communication, and user status) alongside a USER push-button and a RESET push-button.

• Software Support: Fully compatible with a wide range of Integrated Development Environments (IDEs) including IAR, Keil, GCC-based platforms, and Arm Mbed, alongside comprehensive free software libraries and examples provided through the STM32Cube MCU package.
