Alternatively, the power can be applied from the PWR_IN pins of the 44-pin connector (see
section 4.3). The voltage range when powering from the PWR_IN pins is 4.5V to 30V.
Power can be applied from both sources at the same time. On-board diodes prevent short
circuits.
The interface board provides the 3V3 supply to the AsteRx-i3 OEM receiver and a 5V DC
voltage to the VANT pin of the AsteRx-i3 OEM.
