Pressure Sensor require 5V in #21

We need to change the pressure Vin from 3V3 to 5V as this is what the sensor need to operate. Inspection of the schematic shows that having 0-5V in the adc should not break the circuit due to clamp diodes. Though we will not be able to see voltage above 3V3 as the op-amp will rail. In practice on revision 1 we noticed op-amp railing at 2V7.
