As already mentioned, a LED (D3) is connected to GPIO0 and it is used as output state monitor: it turns-on when
a correct power transfer is established between the receiving module and the transmitter, and the output voltage
is enabled. All the settings shown in table 2 (and other additional ones) can be modified in the registers page of
the GUI (see the related GUI user manual for details).
