Current Measurement
For current measurements the carrier provid
es a 10mΩ shunt resistor in the 5V
path supplying the CPU module.
The carrier also provides an I²C current sense amplifier for automated
measurements. See chapter 5.7 for more details.
Voltage Monitoring
The carrier monitors onboard-generated voltages and resets the module in case
any voltage drops below the undervoltage limit:
