 It is the OLED featherwing 128 by 64 display. You can use that STEMI QT port to add another peripheral. So this is Bongo Cat. And if I hold these, these are gonna play a little sweep on the original Game Boy audio hardware. The extra bonus here is that you can see I've plugged into the STEMI QT port a little accelerometer. And as I tilt that accelerometer, it's a variable that changes the rate of that sweep. It's pretty short sweep if I'm at one, gets a little longer and even longer. On the side of the OLED, same pins as my feather, neokey feather there. OLED featherwing, it's 128 by 64, I squared C display with STEMI QT port.
