3.2.2 Power supply
The default settings use the external power supply from the power jack connector. The
external power supply must always be used, if the DC-DC is enabled (default). The DC
power input can cover a DC voltage around 7.5 V with a current of at least 800 mA. The
polarity does not matter, since there is a rectifier foreseen. The inrush current of the DC-
DC can be up to 1.6 A, when enabling the RF field.
