Hi Rob
I have the same problem about I2C and Robo ph. My board is Rev-E.
Could you send me sketches to update to fix the problem.
Thanks in advance.

Hi Iliyan, I sent the sketch for the controller. It sounds like the buffer isn't close enough to the controller, it might be good if you can shorten the wires from controller to buffer. Also if you move the RTC to the output side of the buffer where the pH plugs in might fix it as well. Either way the sketch should keep it going.
