That board will be definitively somewhat different as they wrote in one of their update that they had to modify it because of some radio/reception problems...
However, I don't know how it affects Pro1.
Generally, I would think the new board may have the very same fixing and conection, but it would be good to know what was the problem with original board and how it may work (better or worse) if it was installed in Pro1.
For example, it may have a charging controller which has some noise what causes problems at some bands of the SDM662-related board... but we know nothing about it.
