+As it turned out that the radio power amplifier was not connected in test #2, i reran the test. Power is provided by the laboratory power source @ 12.3V + DCDC Converter @ 5V for the cm4 board.
+**NOTE:** The sligtly incread Idle power usage is due to the additional DCDC converter, and the powermeasurement BEFORE this converter.
