 How related was this? This is a Grove feather wing. So this is the seed Grove standard, which uses this kind of like funky connector. And there's like hundreds of Grove sensors available. They tend to use an analog input, but some use two digital, some use I squared C. This OLED here uses the I squared C connection. So this is, there's four analog ports, sorry, three analog ports, one UR port and two I squared C. So this one has just one SSD 1306 library. And then here I have a Grove rotary encoder and I just have some code that is upside down that's reading it using a circuit python running feather M4. So, oh, I also added a STEMI QT port. The N had just enough space for a little vertical one. So you can see here the markings that this is like RXTX, two I squared C, this is A0, A1, two A3, A4, A5. So this prototype is working and gonna be in the shop soon. Great for getting your existing Grove stuff working with feather.
