Power supply and power selection

6.5.1

External power supply input

The STM32 NUCLEO-G070RB or NUCLEO-G071RB board is designed to be powered by
several DC power supply. It is possible to supply the STM32 NUCLEO-G070RB or
NUCLEO-G071RB board with any of the following sources:
•
5V_USB_STLK from ST-LINK USB connector
•
VIN (7 V - 12 V) from Arduino connector or ST morpho connector
•
E5V from ST morpho connector
•
5V_USB_CHG from ST-LINK USB
•
3.3 V on Arduino connector or ST morpho connector
Note: If an external 5 V DC power source is used, the Nucleo board must be powered by a power
supply unit or by an auxiliary equipment complying with the standard EN-60950-1:
2006+A11/2009 and must be safety extra low voltage (SELV) with limited power capability.
The power supply capabilities are showed in
