7.1 Power supply and consumption
7.1.1 Power supply
The power 5V will be injected into the system via micro USB connector of the Nucleo shield
(blue board) from an external adapter. The max rated current of this adapter is suggested to be more
than 1A. The Nucleo board (white board) should be powered by the supply from the shield board. So
the Nucleo board (white board) would be power supplied by VIN (Pin15 of CN8 on the Nucleo F7
board).
