# Watch your Pi! RPi foundation knows that Micro USB for DC-IN
# is sh*t but also doesn't give a sh*t. Voltage drops caused by
# average USB cables cause all sorts of instabilities and also
# data corruption but instead of fixing the problem they masked
# it in their 'firmware'. The main CPU on the Raspberry monitors
# voltage drops and then acts on accordingly. If heavy voltage
# drops directly after startup are monitored the firmware lowers
# the core voltage available to CPU cores and also caps CPU
