About this product
The NUCLEO-F446RE is a Nucleo-64 development board built around the STM32F446RET6 Arm Cortex-M4 microcontroller. It includes an onboard ST-LINK/V2-1 debugger and programmer, so no external probe is needed, and offers Arduino Uno V3 and ST morpho header connectivity for expansion. It works with the STM32 HAL library and mbed.
