well, regardless, it's too late. there will be no further changes

no it does not. the diode does the job.

a 3.3v point is not necessary.

tough. they can be solved. "ease" has nothing to do with it. it's too late.

the answer's no. it's too late. this should have been raised 18-24
there will be no changes.
