Automation pHat ADC Extra


#1

The documentation says there is a third ADC “on the header.” Where, exactly? I’m measuring a voltage between 0 and 1.5 and the divider allowing 0-24 volt range is making the steps too large to be useful.


#2

Correction. Three ADCs use the 0-24v range. I’m looking for the fourth one that isn’t available at the screw terminals.


#3

This is referring to the HAT, not the pHAT. The pHAT doesn’t break out the remaining ADC pin.


#4

Thanks! I’ll either amplify the signal or use a different sensor.
