@insight3fl I uploaded the "Buzzer test" .ino and it successfully loaded ran, and shows "Button Test" across the display. That said, none of the rest buttons seem to function so every time I turn on the device, the sketch is still running and showing the "Buzzer Test" and beeping of course.

How do I restore the Cardputer to factory default? Pushing the go button while turning on does not seem to work.

Thanks for helping a newbee!

You'll need to re-upload the factory firmware. I think I saw someone uploaded it 3rd party in M5Burner. If not, I ripped a clean copy of my firmware and I'll share it tomorrow. Just click "ALL" and then search "cardputer" in the search box on the M5Burner app.

@4x0nn Thanks! Obviously I am a newbee and have much to learn.

@insight3fl burner was fast and easy to retore factory default including a few extras like wifi connect. There is also one other Burner program "Nemo" that works great. I hope for us newbees there will be more packed tools. I am receiving an order today for RFID, Enviromental, motion and a few other plug in modules.

Thank you
