Figure 9. STM32G4 Nucleo-64 board power tree

In case 5V_VIN, E5V, 5V_USB_CHGR, or 3V3 is used to power the STM32G4 Nucleo-64 board, this power

source must comply with the EN-60950-1: 2006+A11/2009 standard and must be Safety Extra Low Voltage

(SELV) with limited power capability.

If the power supply is 3V3, the ST-LINK is not powered and cannot be used.

Power supply input from STLINK-V3E USB connector (default setting)

The STM32G4 Nucleo-64 board and shield can be powered from STLINK-V3E connector CN1 (5 V) by placing a

jumper between pins 1-2 of JP5, “5V_SEL”, as illustrated in Figure 10. This is the default setting.
