High-performance ARM Cortex-M4 development board

The MCDODO STM32 Nucleo-F446RE board provides a high-performance foundation line featuring an ARM Cortex-M4 core with DSP and FPU. It includes 512 Kbytes of Flash memory and runs at 180 MHz with an ART Accelerator. This board suits engineers and makers prototyping embedded applications that need floating-point and signal-processing capabilities.

On-board ST-LINK/V2-1 debugger with SWD connector

Programming and debugging rely on the integrated ST-LINK/V2-1 debugger and programmer accessed via an SWD connector. The board can be powered directly from the USB connection used for the debug link, removing the need for an external supply during development. Support spans a wide choice of IDEs including IAR, ARM Keil, and GCC-based environments.

Dual QSPI interface and user interface elements

Dual QSPI support enables connection to high-speed external flash or RAM for storage-heavy firmware. Three on-board LEDs and two push-buttons give immediate visual feedback and manual control without extra wiring. The Arduino-compatible header layout simplifies stacking shields or attaching custom circuits for rapid iteration.
