A number of modules I've seen are annoyingly very close but not identical.
Nothing a needle file can't fix.

I found the PLED module added enough noise to the power rails on the P3
mainboard to affect the ADC conversion for the pots.
It may or may not be an issue in other designs. Since the Virus is all
digital, I imagine it's probably OK, and they may have (sensibly) de-coupled
the display module supply already.
