Figure 13. JP4: 5V_USB_CHGR selection

Note: If the board is powered by a USB charger, there is no USB enumeration, so the LD3 LED remains OFF

permanently.

Caution: Do not connect the PC to the CN8 ST-LINK connector. The PC might be damaged or the board might not be

powered correctly.

The LD5 green LED is lit when the B-U585I-IOT02A Discovery kit is powered by the 5 V correctly.

The power tree is shown in Figure 14.
