{{InternalInfo|CN3 could be used to connect a CR2032 lithium battery, wired on a Molex Picoblade 2 circuits pitch 1.25mm type 51021-0200  (1-VBAT, 2-GND).<br/>Like Thinkpad 02K6541, 02K6572, 02K7075, 02K7087, 08K8050, 92P0986, 92P0991 models. }}

Details of some LEDs:
* <span id="LD1">LD1</span>: red if USB type A connection established
* <span id="LD2">LD2</span>: green if power connection established
* <span id="LD3">LD3</span>: green flashing the Ethernet connection established
* <span id="LD4">LD4</span>: red flashing if ST-LINK/V2-1 connection not established, else green
* <span id="User LEDs">LD5, LD6, LD7, LD8</span>: 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
