SK6812MINI-E Logic Voltage #3

Description

@jyancat

In https://github.com/FrameworkComputer/InputModules/tree/main/Electrical/MicrocontrollerInputModule there is a SK6812MINI-E RGB LED driven by 3V3 logic, while this probably will work it's not optimal, better to add a level shifter (up to 5V logic) or note this in the folder readme.

    The datasheet specifies that VIH is "3.4V typical" so yeah, this is technically operating the SK6812 out of spec.

    A 74LVC1G34GW would be a compact solution.

    this probably will work

    You're right, it does work :D

    This really is just a quick and dirty reference that's not supposed to be used for anything and also supposed to be as simple as possible.
    We made a couple test boards to see if it works, but nothing more.

    So if you could make a PR to add a level shifter that would be great.
    Otherwise I think we'll just add a comment to the README noting that the design is functional but perhaps not optimal.
