SK6812MINI-E Logic Voltage #3

Open jyancat opened 1 year ago

jyancat commented 1 year ago

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. Screenshot from 2024-01-24 18-31-26

A 74LVC1G34GW would be a compact solution.
