Sample rate is 40hz, resolution is 1/8 amp. Latency seems to be less then then the sample rate, we compared it to an analog current sensor we used last year and didn't see any unexpected latency. I haven't seen any specs on max current, but it measured 60+ amps per channel on our drivetrain.


I've attached data we collected from the PDP during a match at the SCRRF Fall Classic. Note that each channel has a small steady state error, which will be calibrated out in a later firmware update.
