Measuring currents on multiple rails, particularly if something like an Arduino or Raspberry Pi is expected to collate the information, can take a fair amount of circuitry and calibration. An evaluation kit (INA296AEVM) that has just appeared from TI (supposed to cost $49) has three almost-complete precision current sensors that will give ground-referenced outputs, and …
