The EETI touchscreen needs calibration after assembly, otherwise there may be dead zones or other mis-tracking.
It would be good to do it during factory test.
That said, I wonder if the calibration might drift before the unit is deployed, maybe as a result of temperature, altitude, humidity, shipping conditions, or other factors. So it might be a good idea to recalibrate it somewhere else too, perhaps just before booting, or somewhere in the Linux startup.
