From STMicroelectronics, the NUCLEO-F446RE development board features an STM32F446RE Arm Cortex M4 microcontroller in a LQFP64 package. With unlimited extension opportunities, this board enables you to easily develop, build and evaluate prototypes. The microcontroller is housed in a relatively small package, giving you more development flexibility than larger boards.

Integrated Arduino™ Uno V3 connectivity support and ST morpho headers enable you utilise the STM32 development platform to expand the functionality of your board by connecting to specialised shields.

The NUCLEO-F446RE has an ST-LINK/V2-1 debugger and programmer which means that you will not require a separate probe. Supplied with HAL Library software (and other packaged software examples), you can begin prototyping immediately. You will also have direct access to ARM mbed online resources. A range of IDEs (Integrated Development Environments) such as GCC-basd IDEs, IAR and Keil support this development board.
