  • I don't know what happened with yours fellow plane enthusiast, but in my case the first of two did not work. Second was found and displayed dumps to indicate finding the button chosen and a display.

  • Has anyone ever used one of these? The "friction fit" doesn't seem to have any friction at all. Sitting over the pins, it just wiggles at will, and the power lights on my QWIIC modules are turning on and off, etc.. It even has caused the PI to reboot twice.. What am I missing? When I ordered this, I kind of expected a spring-type interface or something, but no such luck! I'm thinking maybe I just need to solder this to some arduino style headers, so that I can plug the entire header in and have a solid connection, but I'd love to hear someone else's experience..

    • Hi 172pilot,

      We certainly have used these on many different Pi's without any issues. In fact, I've got one on my Pi 3B+ I use for testing Qwiic products at my desk. The SHIM should fit snugly on your Pi's GPIO header when pressed down to the black plastic at the base of the pins. The friction fit is designed to press slightly against the pins and hold it in place with no other hardware or springs. If you're noticing the SHIM wiggling about and pressing it down to the black plastic at the base of your GPIO header does not help, a quick fix would be to carefully adjust the pins on your GPIO header so they make better contact with the SHIM. I hope this information helps you (and possibly other users) get your SHIM working properly.
