The INA3221 or rather one of the boards based around it, allows for a single power input and up to 3 power outputs –each monitoring voltage and current and all done via I2c. You can (almost) think of this as a triple INA219 – the bidirectional current power monitor.
 
3 Channel Current Sensor INA3221 I2C (High Side DC Current) / Measure Module for Current
 
With this Breakout / Sensor you solve all your power monitoring problems! Thanks to the INA3221 IC, you can measure voltage and current and pass it on to a microprocessor via I2C or SMBUS.
 
The INA3221 senses current on buses that can vary from 0 V to 26 V.
 
The device is powered from a single 2.7-V to 5.5-V supply, and draws 350 µA (typ) of supply current.
 
The INA3221 is specified over the operating temperature range of –40°C to +125°C.The I2C- and SMBUS-compatible interface features four programmable addresses.
