 The Quad Rotary Encoder Breakout Board with StemAQT and iSquare C. So this allows you to use rotary encoders with the little push button, and it gathers up all the data from those four encoders, sends that message over iSquare C to your microcontroller. So what I've got here, a little QtPi with the StemAQT connector that is running to a little 14-segment Alpha numeric display, and then I have my breakout board for the Quad Rotary Encoder. One of the advantages of using encoders over something like a potentiometer is we have definitive stops. So each little kind of click that I get to, we can update some value. So in this case, I'm just sort of using these as a little animated indicator. And then we also have the little push encoder so I can click on those and get the little dot sign to show up. It is the Quad Rotary Encoder Breakout with StemAQT over iSquare C and underlit Neopixels.
