27. WAKE UP button:used as regular button, and/or wake up the STM32 MCU from sleep
28. USB to UART jumper
29. LED jumper
    • short the jumper to connect to default I/Os used in example code
    • open the jumper to connect to custom I/Os via jumper wires
30. Button/Joystick jumper
    • short the jumper to connect to default I/Os used in example code
    • open the jumper to connect to custom I/Os via jumper wires
