LED1
State indicator
This indicator is on when the expansion card is establishing a
connection with the control board; it blinks periodically after
the expansion card is properly connected to the control board
(the period is 1s, on for 0.5s, and off for the other 0.5s); and it
is off when the expansion card is disconnected from the
control board.
LED4
Power indicator
This indicator is on after the IO expansion card is powered on
