Cut able PCB

The NUCLEO-G070RB or NUCLEO-G071RB board is divided into two parts: ST-Link part
and target MCU part. ST-Link part PCB is cuttable to reduce board size. In this case the rest
target MCU part is only powered by VIN, E5V & 3.3V on morpho connectors CN7 or VIN &
3.3V on Arduino connector CN6. And it is still possible to use ST-Link part to program the
main MCU using wires between CN7 and SWD signals available on morpho connectors.
