Hi! I'm having an issue with one of my FED3 devices that consistently fails to recognize the SD card. I've tried multiple SD cards and I also replaced the Adafruit Feather M0 Adalogger with one from a fully functional FED3, but the issue persists.

I'm wondering if there are any other components or troubleshooting steps I could try before giving up on the device. Has anyone encountered a similar issue or found a way to repair it?

Thank you!

Laia
