Wow, thanks Zitron, you are my hero. Just a couple of questions if I may:

- Is the board V_in really +3V? I would have thought it was +5V (it must get regulated down somewhere on the processor board?)
- Is Ref Voltage (V_ref) output generated on board, or is it an input generated external to the board?
- What does the 103 trimmer you added do (does it divide down V_in to set V_ref?)

Thanks again.
