The "NUCLEO-L152RE" is an STM32 Nucleo development board featuring an STM32L152RET6 MCU, which allows users to create prototypes for embedded applications. It offers Arduino connectivity support and ST Morpho headers, making it easy to expand the functionality of the STM32 Nucleo open development platform with various shields. The board integrates the ST-LINK/V2-1 debugger and programmer, eliminating the need for a separate probe. The STM32 Nucleo board series is based on ARM Cortex-M 32-bit RISC cores optimized for high performance and energy efficiency. The ARM Cortex-M core features a high-density instruction set and an Nested Vectored Interrupt Controller (NVIC) for excellent interrupt handling capabilities.
