Measuring the current flowing to the brushless motors

We’re looking to install the AttoPilot Voltage and Current Sense Breakout to each of the 4in1 ESCs board on the Iris, but we are not sure if we could use any of the Pixhawk analog inputs to monitor/record the current values as telemetry.

Does anyone have suggestions on how to measure the current flowing to each of the brushless motors of the Iris?
