The NUCLEO-L073RZ is a STM32 Nucleo development board with ultra low power STM32L073RZ MCU allows user to build their own prototypes for embedded applications. The Arduino connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo board series are based on ARM Cortex-M0+ 32-bit RISC cores optimised for high performance and energy efficiency. ARM Cortex-M features a high density instruction set and a Nested Vectored Interrupt Controller (NVIC) providing excellent interrupt handling abilities.
