    1) There is only 1 reset button, the other is User button

    2) This may help:

    3) It will depend on what MCU is doing and what is connected to the board. There are many articles about it, for example, this may help (says 30mA - 50mA / 5V):

        You can use the button any way you like (depends on your firmware)
