What to do with the last ADC input?

We have an extra ADC input - what can we do with it?

  1. Nothing
  2. Detect what voltage is present in the AUX PSU.
    • can be used for troubleshooting (recommending additional PSU, scaling calibrations to new voltages)
  3. BOM version
    • don't value this much, as our BOM is likely not going to change between board versions
  4. header pin for aux sensors.
    • list any sensors that provide a voltage between 0 and 3.3V:

I think the best solution is 1. The ADC will be configured and optimized for reading OD readings from the op-amp - I don't want other processes breaking this.
