Currently I am working to bring Wi-Fi connectivity to the Tufty 2040 via I2C using another amazing board, the Adafruit Qt Py ESP32-S2. It is being full of challenges, but I am learning a lot!

I was already printing the case and this ESP32-S2 Feather was just collecting dust so I'm still gonna make some kind of little toy with it. I love the case design and think it came out alright in spite of my printer issues. Can't hook up the battery yet tho until I program in a sleep mode lol
