Hi jlysaght3, I'm neutral on where to mount it, basically what fits your setup best. I've tested the circuit around other electronics and they don't interfere. I always assumed adding an extension cable would have negative effects as the signal from the probe would degrade before getting to the circuit but my probe has maybe 15 ft of cable and I've attached a 25ft extension which had no effect on the reading so yeah setup didn't have much to do with anything.
I think you have the thinner case so there isn't a lot of room but it should fit in line with the RTC battery as the circuit is about the same height as the mini w5100. Maybe place a piece of box board between the pH circuit and controller board so there's no chance it shorts out with the solder joints on controller. The spare SCL/SDA pins next to the w5100 are on the output side of the buffer giving them 5v so connect the pH to 5v power on controller.
