Hey Rob,
So I decided to mount the pH circuit inside of the slim case for the Robo-Tank. I chose to pull the board out of the case and mount the circuit underneath the board when viewed from the bottom (between the main shell of the case and the circuit board, as opposed to between the board and the cover/bottom of the case).
I soldered wires directly to the jumper pins on the circuit, and then to the main board in the controller giving me a total of <6inches (15mm) cord length between the controller and the circuit. The added benefit is that the pH probe connection is on the side of the controller facing my tank, and I keep both USB ports for accessories open for power bars and other add-ons.
I also did this so that when you have an EC board and DO board (electrical conductivity + dissolved oxygen) I can also add them into the controller case and have everything fit with shortest cables + seamless integration.
I have included pictures for reference. I think that the controller case can easily support 2 circuits behind the board, and possibly another 1-2 on top of the board for a total of 3-4 (this would account for a pH, DO, EC, and possibly an ORP all native in the case, each with full isolation + easy access connections).
PS: Filling in the recessed Robo-Tank logo makes the controller look really cool!
