To measure the power consumption of the AsteRx-m2a OEM board (excluding the
contribution from the DevKit and the antenna), remove the jumper on J200 and connect
the two pins to the probes of a multimeter in current-sensing mode. Measure the current
flowing between the two pins and multiply it by 3.3V to obtain the power consumption.
It is recommended to set the multimeter in high ampere setting to keep the voltage drop
as low as possible.

Antenna Connectors
There is no antenna connector on the DevKit. The antennas must be connected directly
to the u.FL connectors on the OEM board. See section 2.4 for details.
The DC voltage (5V or 3.3V) at the antenna connectors is determined by the position of
the jumper on header J204, as shown below.
Vant = 5V
Vant = 3.3V
The jumper can be removed if the antenna does not need to be powered by the receiver.
In that case, there is no DC voltage at the antenna connector.
