The previous photo from the top of the board, looked like the red and blue wires (which I thought were the power) were coming from the middle of the board and there were two black wires coming from one end. That's what I meant about having to actually be there to see what was what....
Anyway did you try the single wire on a bare connector thing? The Photo/Temp sensor is on the micasb sensor board -- the MTS300 or 310...I keep loosing track of the part numbers. I think the MDA300 also has them, but can't find any actual schematics. The only ADC connections on the mica2,z boards themselves are Voltage at ADC7 and RSSI at ADC0. I presume that the IRIS board is the same, and also that it has the same 52 pin expansion layout. I think you stated that you were able to read the sensor- board Photo/Temp correctly, without Voltage value interference. And also that you were able to read Voltage when there was no sensor board attached. This leads me to believe that the problem is in the element that changes: your break-out-board. Probably the thing to do at this point is back-up to the beginning and try everything again, changing only one element -- both software and hardware -- at each step. Debugging this stuff by remote control is basically impossible though.
