Thread: Mordax Data has 2 power settings
Definitely a better use for the 5V rail! And given how much current that often gets hidden on that rail, it surprises me that pretty much no one else has tried a powering method like that. You sometimes see the 5V rail used to power the filaments on tube-based modules, or when there's a little processing chip onboard that needs it. But outside of that, nothing much, so this is a good trend, IMHO.
