I think it would be more accurate to say say "once you add an active power supply to PWM signals from the MXP ..."
This does not keep you from supplying 3.3v or 5v from the MXP header or battery voltage from the PDP to the DIO pins, It only keeps you from adding a power supply to add a different voltage.

No matter what board you use, if you claim that it is passive, you'll have to prove it at inspection. Not sure how having a prototyping area changes that. An active circuit added to a prototyping area of an otherwise passive board makes it active.
