Grove - PH Sensor Kit (E-201C-Blue) Input voltage affects output?

Hey guys, I’m looking to integrate this product on my Arduino MKR Zero prototype (It’s a 3.3V system).

I already printed the PCB for the shield and made the mistake (or maybe not) of powering the grove lines with 5V instead of 3.3V, glancing at the schematics I see that there’s voltage conditioning onboard of the controller. I’m not really good interpreting the whole schematic and wanted to ask you guys, does feeding the circuit 5V affects the output range? I.E. changing the range from 0V-3.3V to 0V-5V

Hi there,

This sensor can work with both 3.3V and 5V systems. And 5V doesn’t change the output range. Because it will be shifted to 3.3V then supply to the chips.
