Supply current
The supply current is measured on the SoM using the following commands:
Stresstest on all 4 CPUs:
stress-ng --matrix 0 -t 0
Stresstest on all 4 CPUs and RAM:
stress-ng --matrix 0 -t 0 --vm 4 --vm-bytes 50%

The current of the RTC is measured with VCC_IN_5V supplied with +5V and while power off. RTC_PWR is supplied
with +3.0V.

Output Voltage
The SoM has some power output pins that can be used on the baseboard. The voltage test pins VCC_6_TEST (C5) and
VCC_5_TEST (Y3) can also be used, all other VCC_X_TEST pins should not be used.
