@kuriko So you are saying it is a software issue rather than hardware which seems to be the case to me. It would be really helpful to have access to the source for the unit classes so I could add functionality through inheritance.

Hi guys have you tried the RGB module in Hardware? Works fine for me. I created an example using an M5Atom to control 10 SK6812 RGB LEDs. You can find it in the UIFlow2 Project Zone: M5Atom_RGB_Test_UiFlow2.3.3 Thanks Felix
