Figure 13. Jp6 [9-10]: 5V_Chgr Power Source - ST STM32U5 User Manual

5V_CHGR is when a DC power charger is connected to the USB STLINK-V3E connector (CN1). To select the
5V_CHGR power source, the 5V jumper selection (JP6) must be between pins [9-10]. If an external USB charger
powers the STM32U5 Nucleo-144 board, then the debugging feature through (CN1) is not available. If a host
computer is connected instead of the charger, the current limitation is no more effective. In this case, the host
computer can be damaged, and it is recommended to select 5V_STLK mode.
5V_CHGR configuration: 5V jumper selection JP6[9-10] should be connected as shown in
Note: With this JP6 configuration, the USB_PWR protection is bypassed. This configuration is forbidden to power the
board with a computer USB port, as the USB_PWR_protection is bypassed. The reason is that if the board
consumes more than 500 mA, it can damage the computer.
