The ecosystem builds on ST’s STM32Cube platform. This comprises the STM32CubeMX initialization code generator and configurator, and the STM32CubeL4 package that contains middleware components, Nucleo-32 BSP, HAL, and LLAPIs.
The slim form factor NUCLEO-L432KC board – the first Nucleo-32 board to integrate an MCU in the tiny QFN32 package – includes an STM32L432KCU6 device (UFQFPN32) and provides direct access to ARM mbed online tools. Its Arduino Nano pin layout simplifies function extensions, and the integrated ST-Link debugger/programmer supports mass storage and allows probe-free debugging.
