Power Monitoring
The CPU Board has provisions for power monitoring using INA226. The measurement system is
consisting of the TI INA226 I2C current shunt/power monitors. The INA226 device provides both power
supply voltage and shunt current measurements, as well as calculated power via an I2C bus. This allows
the device to be placed close to the shunt.
