This STM32 Nucleo-144 board provides an affordable and flexible way for users to build prototypes with the STM32F446ZET6 microcontroller. The Zio connector, which is an extension of Arduino Uno, provides access to more peripherals and with the ST morpho headers expands the functionality with a choice of Shields. The integrated ST-LINK/V2-1 debugger/programmer comes with the STM32 comprehensive software HAL library, software examples, as well as direct access to the ARM mbed on-line resources. Supported by wide choice of Integrated Development Environments (IDEs) including IAR, Keil, GCC-based and ARM mbed.
