Lex Kravitz designed a small PCB for flipping the orientation of a feather board that is useful for flipping the orientation of a camera or screen wing:
I wanted to use an Adafruit AMG8833 thermal camera feather wing with the mini color TFT feather wing. Stacking them together with a Feather doubler board works fine (and the AMG8833 data looks very nice on the tiny screen!) but the problem is that the thermal camera is looking in the same direction as the screen. When you look at the screen all you see is…. you!
