In the project will have 4 INA226 modules each of which has a different power supply (12V, 5V, 5V USB and 3.3V). I am attaching the wiring diagram of all 4. At the moment, however, I tried only a connection of 2 of these modules to see in the meantime if the Arduino code worked (if it works for 2 it also works for 4) but it doesn't work ☹ I found the i2c addresses with the I2C Scan code and then corrected them (one. The Texas Instruments INA226 Current/Power Monitor IC senses current on buses that can vary from 0V to +36V. The device obtains its power from a single +2.7V to +5.5V supply, drawing a typical of 330µA of supply current. The INA226 is specified over the operating temperature range of -40°C to +125°C

  1. The INA260 avoids these limitations, and with it's integrated precision shunt resistor it can be used to measure as much as +36V at up to 15A Continuous on either the high or low side
  2. If your shunt is high-side (in the + line), then the INA226 can measure voltage and current. In that case battery voltage is limited to 36volt. In that case battery voltage is limited to 36volt. If the shunt is used low side (in the ground line), only current can be measured

Programmable calibration value, conversion times, and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts

looking at the data sheet for the INA3221 the max shunt voltage is Full-scale range = 163.8 mV so your sums add up but the 0.1R resistor is too big to measure anything over 1.6A as you will hit Full-scale on the input. change them to 0.01R or a value to give just less then 163.8mV 20% or so above the largest current you want to measure. regards Nei As for calculating a shunt resistor, you could use the following method, divide the max Vsense voltage of the INA226 (.08192V) by your max current.036A. This will give you a value of 2.276 ohm. According to Figure 1 in the datasheet, the gain is 1 up to ~100KHz .
