Figure 13. JP6 [7-8]: 5V_USB_C Power source
5V_CHGR is the DC power charger connected to USB ST-LINK (CN1). To select the 5V_USB_CHARGER power
source on the JP6 silkscreen, the jumper must be on pins [9-10]. In this case, if an external USB charger powers
the Nucleo board, then the debug is not available. If a computer is connected instead of the charger, the current
limitation is no more effective. In this case, the computer can be damaged and it is recommended to select
5V_STLK mode.
5V_USB_CHG configuration: Jumper JP6 [9-10] must be connected as shown in Figure 14.
