Details of some LEDs:

  • LD1: red if USB type A connection established
  • LD2: green if power connection established
  • LD3: green flashing the Ethernet connection established
  • LD4: red flashing if ST-LINK/V2-1 connection not established, else green
  • LD5, LD6, LD7, LD8: some user LEDs are used to reflect the system activity, whereas the others are left free and can be directly used by the application, as explained in the LEDs and buttons on STM32 MPU boards article
