Proffie SwitchBack

The Proffie SwitchBack will look something like this:

It’s 13mm in diameter, and fits on the back of a 16-mm AV button with an common-anode RGB led inside it. On the other side of the board, there will be a WS2811 chip and a data resistor.

I will post progress in this thread, which I hope will end with a run. :slight_smile:


Assuming that the legs for the LEDs vary between switches, would there be jumpers from the RGB outputs of the WS2811 to route to the correct legs?

Edit: Also could consider a 12mm variation if this works out since those are seemingly more common for builds with AV switches

This PCB will assume that the legs are in a particular order.
The switches I have are all +/R/G/B, so hopefully that is what most switches do.

I have not seen any RGB 12mm switches, do you have a link for one?
Also, the chip I’m using will probably not fit between the legs of a 12mm switch, so it might be difficult.

There are some smaller WS2811 chips available though. They just aren’t as easy to find in stock.
