 It is the ATtiny 817 seesaw breakout board. What we've developed and we use on here a lot is the seesaw framework. That is a I squared C to anything protocol. This is the RP2040 QDPI. I'm just speaking I squared C between these two things. A lot of the heavy lifting is right here on the seesaw board. So I'm reading a potentiometer and I'm taking those analog values and I'm actually converting them into PWM values to change this brightness on my yellow LED here. I'm reading this little switch here. This is actually a neopixel right over here and my potentiometer is serving double duty. When I'm in this mode, I can change the speed of a fade between a couple of colors or three colors to be precise. It's the ATtiny 817 seesaw breakout board.
