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.
