Nucleo family of boards by STMicroelectronics with mbed IDE development. The Nucleo board has an onboard ST-LINK/V2-1 host adapter that supports SWD debugging / virtual COM port / mass storage. Each board has Arduino female headers and a new STM32 Morpho connectors consisting of two 19x2 male pin headers. The PCB uses a common layout that supports many STM32 series.
