Hello, this was written several years ago but can you tell me why you have RGB pins going to pins 10, 11, and 12 instead of just Ground? Why did they make the PCB this way? Is there an advantage to connection the ground to GPIO pins? I will experiment a bit and maybe get the answer myself.

OK, pins 10, 11, 12 set the color. The other bits select which LED(s) to light. Why did I think RGB could have just gone to ground and control should have from the other pins? There are examples out there have have a common pin and change colors. Here - https://www.hackster.io/AlexanderVaughn/not-your-typical-rgb-led-356854 What am I missing here?
