The NUCLEO-F446RE development board features an STM32F446RE Arm Cortex M4 microcontroller in the LQFP64 package.
This board has unlimited expansion opportunities, making it easy for you to develop, build, and evaluate prototypes. The microcontroller is installed in a relatively small package, giving you more development flexibility than a large board.
Connection support and ST morpho headers enable you to leverage the STM32 development platform to extend the functionality of your board by connecting to specialized masking devices.
NUCLEO-F446RE has a ST-LINK/V2-1 debugger and programmer, which means you don't need a separate probe. With the HAL library software (and other packaged software examples), you can start prototyping immediately. You also have direct access to ARM mbed online resources. A range of ides (Integrated development environments) such as GCC-basd IDE, IAR and Keil support this development board.
