Sorry all, I failed to RTFM completely!
From the documentation-->"For your convenience it is calibrated to be 3.3V when the channel is delivering its maximum possible current, that is 2A"
Therefore: 0 to 1023 = 0 to 2 Amps
2/1023 = .00195
So analogRead(0) * .00195 = Amps
Disapointing to have such poorly represented hardware on the manufactures website/ forum.
In the future where should I go to get accurate info on arduino products???
